Answer

A project has PV 200, EV 150 and AC 180. Is it ahead or behind schedule, and over or under budget?

Work through the formulas.

  • SV = EV - PV = 150 - 200 = -50, and SPI = 150 / 200 = 0.75. The project is behind schedule.
  • CV = EV - AC = 150 - 180 = -30, and CPI = 150 / 180 = 0.83. The project is over budget.

Engineering Manager

ExperiencedMost askedScenario
Answer

Product wants a big feature launched next month, but the team says a fragile module will break under it. What do you do?

I would check the risk first. Then I would give the business a choice with numbers, not a refusal.

  1. Ask the engineers to put numbers on it: what fails, how likely it is, and what a failure costs (downtime, bad data, support work).
  2. Look for a smaller option. Ship the feature as a thin slice behind a feature flag. Fix the fragile module only where the feature touches it.
  3. Show the product owner two or three options: full scope later, reduced scope on time with named risks, or on time with extra people. Include effort, risk, and what we stop doing.
  4. Write down the decision, including the monitoring and rollback we will have.
  5. After launch, schedule the proper fix so the shortcut does not become permanent.

Good judgement here means I do not simply side with engineers or with product. I make the trade-off clear. The person who is accountable decides with full information. Then I fully support that decision with the team.

What they are checking: Whether you handle engineering versus business tension with options and ownership, not conflict

ExperiencedMost askedScenario
Answer

One of your engineers has been underperforming for two months. How do you handle it?

I start by understanding. Then I make expectations clear, then I support, and only then do I escalate.

  1. Check the facts. Compare against the role expectations with examples (missed deadlines, review quality, bugs), not impressions. Rule out my own failures, such as unclear goals or the wrong task for the person.
  2. Talk in private. Describe specific things I saw, ask for their view, and listen for causes. These may be personal issues, a skill gap, unclear priorities, or burnout.
  3. Agree a written plan: 30 to 60 days, clear measurable outcomes, support (pairing, training, smaller scope), and weekly checkpoints.
  4. Give feedback often and write it down. Involve HR early if it may become formal.
  5. Decide. If they improve, recognise it in public. If they do not improve despite support, move to a formal improvement process or an exit. Handle it with respect and follow the law.

Meanwhile I protect the rest of the team from quietly carrying the load. The goal is to give a fair chance to succeed. But keeping a long-term underperformer also harms everyone else.

What they are checking: Whether you balance care, clarity, and fairness, with written steps and an end point

ExperiencedMost askedScenario
Answer

Your project is two sprints behind and the deadline is fixed. What do you do?

First understand why. Then choose among scope, time, people, and quality, with the stakeholder involved.

  1. Find the cause. Was it scope growth, wrong estimates, dependencies, people leaving, or rework from bugs? Use the sprint burndown and blocked-item data, not guesses.
  2. Reset the plan. Re-estimate the remaining work, rank it by value, and find the smallest release that still works.
  3. Show the options. Cut or delay lower-value scope (usually best), move the date, or add people. Explain that adding people late often slows delivery because of onboarding cost. Overtime and cutting tests create hidden debt.
  4. Remove blockers myself. Escalate dependencies, shield the team from new requests, and simplify the process.
  5. Tell people now, and then every week: what changed, the new forecast, and the decisions needed.

The wrong path is staying silent and hoping. Early honest news gives stakeholders options. Late news only gives them surprises.

What they are checking: Whether you find the cause, offer trade-offs, and communicate early instead of asking for heroic overtime

Answer

Your product must handle ten times its current traffic in three months. How do you plan the scalability work?

I would measure first, then fix the real bottleneck, then prove it with load tests.

ExperiencedMost askedScenarioFree with sign-in
Answer

Two senior engineers on your team disagree strongly on a design and the argument is stalling the project. How do you resolve it?

I separate the technical question from the personal friction. Then I drive to a decision with a deadline.

ExperiencedMost askedScenarioFree with sign-in
Answer

The same type of incident has happened three times in two months despite postmortems. What do you do?

Repeated incidents mean the postmortem actions are not working. So I look at the follow-up process itself.

ExperiencedMost askedScenarioFree with sign-in
Answer

A feature is late and a non-technical executive asks you to explain why. How do you communicate it?

I lead with the impact and the plan. Then I give the cause in plain words. I never surprise them.

ExperiencedMost askedScenarioFree with sign-in
Answer

A developer merged AI-generated code that caused a production bug, and they admit they did not fully read it. What do you do?

I handle the incident first. Then I handle the behaviour and the system.

ExperiencedMost askedScenarioFree with sign-in
Answer

Your strongest engineer tells you they are resigning. How do you respond?

First I listen. I do not react defensively and I do not rush to make a counter offer.

ExperiencedMost askedScenarioFree with sign-in
Answer

An API endpoint has become slow and users are complaining. How do you guide the team to diagnose and fix it?

Answer

You are interviewing for a data engineering manager role. How would you manage a team that owns data platforms and pipelines?

I would manage it like a product team. The users are analysts, data scientists, and downstream services. The main promise is reliability.

Situational

ExperiencedMost askedScenario
Answer

A client asks for a feature to be delivered in half the agreed time. How do you handle it?

I would not say yes or no right away. I would find out what the client really needs and offer options.

  • Ask why the date moved and which part of the feature matters most.
  • Re-estimate with the team and show the critical path (the tasks that set the end date).
  • Offer options: a smaller first release (core flow only), more people where work can run in parallel, or the same date with later phases.
  • Show the cost and risk of each option, such as less testing or more overtime.
  • Agree the choice in writing and update the plan.
  • Track progress daily and report risks early.

The client gets a decision instead of a refusal. The team is not forced into an impossible promise.

What they are checking: Whether you negotiate and offer options instead of just saying yes or no

ExperiencedMost askedScenario
Answer

Production is down on a Friday evening and the client is calling you. What do you do?

First restore the service. Keep the client informed while the team works.

  • Reply to the client within minutes: we know, we are working on it, and the next update is at a set time.
  • Open an incident call, name an incident lead, and bring in the on-call engineers and infrastructure people.
  • Ask for a fast and safe recovery: roll back the last release, restart, fail over, or switch off a feature flag.
  • Keep a timeline and send updates at fixed times (for example every 30 minutes).
  • After recovery, confirm with the client that the service works.
  • Within a few days, hold a blameless review (no blaming people) with the root cause, fixes and ways to prevent it.

My role is to coordinate and communicate, so the engineers can focus on the fix.

What they are checking: Whether you take ownership of incidents with calm and clear communication

Answer

Midway through the project the client keeps adding new requirements. What do you do?

I treat each new request as a change request and show its impact.

  • Thank the client for the idea and ask for the business reason.
  • Check it against the signed scope and baseline.
  • Estimate the effort, cost and schedule impact with the team.
  • Give options: add it with more time or budget, swap it for a lower priority item, or move it to a later phase.
  • Get written approval before starting, then update the backlog or plan.
  • Stop repeats by agreeing a change process and holding regular demos, so gaps show early.

In agile, the product owner reorders the backlog and the team delivers the most valuable work first.

What they are checking: Whether you control scope without damaging the relationship

ExperiencedMost askedScenario
Answer

A team member has been missing deadlines for two sprints. How do you address it?

I find the cause first, support the person, and protect delivery.

  • Talk privately and listen. The cause may be unclear tasks, a skill gap, too much work, personal reasons, or low motivation.
  • Share clear examples of missed commitments and what they affected.
  • Agree goals you can measure for the next sprint, with help such as pairing, smaller tasks, or training.
  • Check progress every week and praise improvement.
  • Move critical work to others so the project is not at risk.
  • If nothing improves, involve the manager or HR and think about reassigning the person.

The tone is fair and supportive, with clear consequences.

What they are checking: Whether you handle performance with empathy and accountability

ExperiencedMost askedScenario
Answer

Two senior stakeholders want conflicting features prioritized first. What do you do?

I make the conflict open and link the decision to business goals.

  • Meet each person alone to learn the real need and the cost of waiting.
  • Compare both requests with the charter, success criteria and company priorities.
  • Estimate the effort and show what each choice delays.
  • Bring them together, or go to the sponsor if they cannot agree, with a clear recommendation.
  • Write down the decision and tell everyone.
  • Look for a phased plan where both get value.

I do not take sides in private, and I do not let the team guess the priority.

What they are checking: Whether you can negotiate priorities using data

FresherMost askedScenario
Answer

Your team missed the sprint goal. How do you handle the review and what changes next?

I am honest about the miss, find out why, and make changes.

  • In the sprint review, show honestly what is done. Unfinished work is not shown as done.
  • Talk to the product owner about reordering the leftover items in the backlog.
  • In the retrospective, look for causes: taking too much work, unclear stories, dependencies, changes during the sprint, or interruptions.
  • Pick one or two actions, for example smaller stories or a time buffer.
  • Use the real velocity (work finished per sprint) for the next forecast.
  • Tell stakeholders what happened and what is changing.

One miss is just data. I watch the trend.

What they are checking: Whether you turn failure into learning

ExperiencedMost askedScenario
Answer

A client escalates to your senior management, complaining about your team's quality. How do you respond?

I listen, own our mistakes, and fix the problem with a plan.

  • First tell my manager the facts: the issues raised, the current status, and what we are doing.
  • Contact the client quickly, listen without defending, and accept their concern.
  • Study the defects and root causes with the team.
  • Share a recovery plan: quick fixes, more testing or code review, one named contact, and a follow-up date.
  • Give regular updates until trust returns.
  • Review the process afterwards so it does not happen again.

An escalation means communication failed earlier, so I also report progress more often.

What they are checking: Whether you stay calm and rebuild client trust

ExperiencedMost askedScenario
Answer

The project is 20 percent over budget at the halfway point. What do you do?

I understand the gap, make a forecast, and share options early.

  • Break down the extra cost: people, vendors, tools, scope growth, rework.
  • Use the cost performance index (CPI) to calculate the estimate at completion. This shows where the project is heading.
  • List options: drop low-value scope, reduce rework with better quality, or change the team mix. You can also renegotiate vendor terms, or ask for more budget with a business case.
  • Take a recommendation to the sponsor and record the decision through change control.
  • Track cost every week.

I never wait until the end to tell people.

What they are checking: Whether you manage budget issues with transparency

ExperiencedMost askedScenario
Answer

You discover a critical defect the day before the release. What do you do?

I check how serious it is and decide with stakeholders, not alone.

  • Reproduce the defect and check the impact: who is affected, is data at risk, is there a workaround.
  • Ask the team to estimate the fix and retest.
  • Give the sponsor and client options: delay the release, release with a written workaround, or release without the affected feature.
  • Recommend one option based on risk and get a decision.
  • If we delay, share the new date. If we release, prepare monitoring and a rollback plan.
  • Add a test for this case.

Hiding a known critical issue is never an option.

What they are checking: Whether you make a release decision openly

ExperiencedMost askedScenario
Answer

You inherit a project that is already late and over budget. Where do you start?

I get the facts before I change anything.

  • Read the charter, scope, plan, budget, risks, issues and status reports.
  • Meet the sponsor, the team and key stakeholders to hear their views.
  • Check the real state: work done, work left, true velocity and team morale.
  • Find the root causes of the delay and extra cost.
  • Build a recovery plan with ordered scope, a realistic estimate, and clear owners.
  • Present it to the sponsor, reset the baseline through change control, and tell the stakeholders.

The first two weeks are for listening and setting a baseline, not for blame.

What they are checking: Whether you can take over and stabilize a troubled project
