Top 3 Critical path Interview Questions
Browse 3 real-world technical and behavioral interview questions about Critical path. Review scenarios, edge cases, and architectural best practices.
A DAG that finished in an hour now takes nine and blocks everything behind it. How do you find out where the time went?
Sum the task durations and compare that with the wall-clock span, because nine hours of waiting and nine hours of work are different problems. If the sum is still an hour, you are queueing on a bounded worker pool, usually behind sensors holding slots; if a task genuinely grew, its own duration history over the last thirty runs tells you whether it stepped or sloped.
A platform team your program depends on has just told you their deliverable will land three weeks late, and it is on your critical path. How do you handle telling the VP the launch date has moved?
Establish the real new date before you talk to anyone, by re-running the critical path with the slip in it rather than adding three weeks to the end. Then present one recommended date with the two rejected options and what each would have cost. It also connects stakeholder communication to the point an interviewer is testing.
How do you turn an effort estimate into a delivery date you would defend, and what do you do when the sales lead has already promised an earlier one?
Convert effort to duration through explicit productive capacity, then check it against the critical path and the customer's dependencies, because dates are often bound by sequence rather than effort. Against a promised date, commit a smaller scope rather than a compressed plan.
