Resolve it with data, then escalate if you must. Show both critical paths, what each project loses, and the business impact of each delay, and ask whoever owns both priorities to choose. Look first for the cheaper fix: resequencing, splitting the work, or pairing them with someone who can absorb the knowledge. Never resolve it by quietly overbooking the person.
Why interviewers ask this
Resource conflict is constant in matrix organizations, and the interviewer wants to see that you make it a business decision rather than a contest of persistence. They listen for creative alternatives before escalation, for impact framed in business terms rather than project terms, and for the refusal to overbook. Candidates who describe winning the resource by being more insistent are describing a habit that damages delivery elsewhere.
How to structure your answer
- Look for the cheaper alternative before escalating.
- Quantify what each project loses in business terms.
- Take both options to whoever owns both priorities.
- Refuse to solve it by overbooking the individual.
Example answer
I resolve it with numbers rather than by being the loudest. So I lay out both critical paths, show what each project loses if it waits, and put the business impact next to each one, then ask whoever owns both priorities to choose. That is genuinely their decision, not mine. Before I go there though I look for the cheaper fix, because a straight either or is usually the worst option available. Can I resequence so my need moves a week, can the work be split so they only do the part that truly needs them, can they pair with someone else for a day so the knowledge is not stuck in one head. On one occasion the specialist spent two days with another engineer instead of two weeks with us, and that was enough. What I will not do is quietly book them at a hundred and twenty percent and hope, because that ends with two late projects.
