Why this exists
MSP interviews are different from corporate IT interviews. They test for billability, flexibility, and tolerance for chaos — things they'd never admit in the job ad.
This guide collects the questions you'll actually hear, what they're really asking, and what the answer tells you about whether you want to work there.
Service Desk / L1 Support ($50K–$70K)
The questions
"How do you handle a user who's frustrated and shouting at you?" - What they're really asking: Can you absorb abuse without escalating? - Green flag: "I stay calm, acknowledge their frustration, and focus on solving the problem." - Red flag: "I'd tell them to calm down or escalate to my manager." (They want autonomous ticket handlers.)
"What's your experience with RMM tools?" - What they're really asking: Have you used ConnectWise, Datto, Ninja, or are we training from zero? - Green flag: Specific tool names + what you liked/didn't. - Red flag: "I'm a quick learner" (translation: no experience, they'll train you cheap).
"How do you prioritise when you have 10 tickets and one user is the CEO's assistant?" - What they're really asking: Can you handle the office politics of MSP work? - Green flag: "I follow the SLA matrix but communicate clearly about expectations." - Red flag: "Whoever shouts loudest gets help first" (they're telling you how it really works).
"Are you comfortable with after-hours work?" - What they're really asking: How much unpaid overtime can we expect? - Ask back: "Is after-hours work paid, TOIL, or expected as part of salary?" - If they're vague, that's a red flag.
"How many tickets do you think you can close per day?" - What they're really asking: Can you hit our utilisation targets? - Green flag: Ask what their average is first. A reasonable target is 8-12/day. - Red flag: "30+" means they're churning and burning.
What to watch for
- Do they mention "ownership" or "growth opportunity" a lot? Usually code for "understaffed."
- Ask about average tenure of the last 3 people in this role.
- If the interview is 15 minutes, they're hiring a body, not a person.
L2 / Senior Support ($70K–$95K)
The questions
"Walk me through how you'd troubleshoot a user who can't connect to the VPN." - What they're really asking: Do you have a methodical process or do you just reboot things? - Green flag: Structured approach — check client config, auth logs, network path, then escalate. - Red flag: "I'd reinstall the VPN client" (treating symptoms, not causes).
"Tell me about a time you automated something and it backfired." - What they're really asking: Do you actually automate, and can you own mistakes? - Green flag: Specific example, what went wrong, how you fixed it, what you learned. - Red flag: "I don't really do automation" or "It never backfires."
"How do you handle a client who insists on a solution that's technically wrong?" - What they're really asking: Can you manage client expectations without burning the relationship? - Green flag: "I explain the risks clearly, document the decision, and offer alternatives." - Red flag: "I just do what they want" or "I refuse and escalate."
"What's your experience with PowerShell or scripting?" - What they're really asking: Can you reduce ticket volume through automation? - Green flag: Specific scripts or tools you've built, even simple ones. - Red flag: "I've run a few scripts" (read: can't write any).
"Describe your ideal ticket load." - What they're really asking: Do you understand the MSP throughput game? - Ask back: "What's the average tickets per engineer per day here?" - If they can't answer, they haven't measured it — meaning it's probably too high.
Senior Engineer / Team Lead ($95K–$130K)
The questions
"How do you keep up with emerging tech while managing BAU workload?" - What they're really asking: We won't give you training time. Can you self-study on weekends? - Green flag: "I block 2-4 hours per week for learning, and I expect my employer to support that." - Red flag: "I study in my own time" (they'll expect this forever).
"Tell me about a project you delivered under budget and ahead of schedule." - What they're really asking: Can you squeeze more value out of thin margins? - Watch for: If they keep circling back to "how did you save money" — margins are tight and they care more about profit than delivery.
"How do you handle a junior engineer who keeps making the same mistakes?" - What they're really asking: Can you manage people or will you just do the work yourself? - Green flag: Structured mentoring — documented process, review, feedback loop. - Red flag: "I'd take over the tickets myself" (they'll pile all work on you).
"What's your disaster recovery experience?" - What they're really asking: Have you actually done DR or just read about it? - Green flag: "I've tested and documented DR plans for X clients." - Red flag: "I understand the theory" (paper DR is useless).
"How do you bill your time?" - What they're really asking: Are you hitting 80%+ utilisation? - Ask: "What's the minimum utilisation target here?" - If it's >85%, they're optimising for billing, not for quality.
Architect / Consultant ($120K–$160K)
The questions
"Design a solution for a 200-user org migrating from on-prem to M365." - What they're really asking: Can you produce billable architecture without supervision? - Green flag: Structured approach — discovery, pilot, migration phases, rollback plan. - Red flag: Missing licensing costs, user training, or support transition.
"How do you handle a client who wants a solution that doesn't scale?" - What they're really asking: Can you sell the right solution or will you just give them what they want? - Green flag: "I explain the cost of rework in 12 months. Sometimes they still choose the short-term option, and I document that."
"Tell me about a time you disagreed with a technical decision from above." - What they're really asking: Will you be a yes-person or do you have backbone? - Green flag: Specific disagreement, how you presented evidence, outcome. - Red flag: "I always follow direction" (lying) or "I went over their head" (can't manage up).
"What certifications do you hold and which ones are you working towards?" - What they're really asking: Are you self-investing or waiting for them to pay? - Ask: "What's the training budget and do you support certification time?" - If they don't answer clearly, you'll be funding your own certs.
Management / Sales Engineering ($130K–$180K+)
The questions
"How do you balance engineering quality with commercial reality?" - What they're really asking: Can you deliver cheap solutions profitably? - Green flag: "I scope properly, document trade-offs, and make sure the client understands what they're paying for." - Red flag: "We do what it takes to win the deal" (you'll be selling garbage).
"What's your approach to team utilisation targets?" - What they're really asking: How hard will you push the engineers? - Green flag: "Targets are a guide. I look at quality, retention, and client satisfaction too." - Red flag: "Everyone should be at 90% or we're not profitable enough."
"Describe your experience with profit and loss management." - What they're really asking: Can you run a contract profitably? - Watch for: If they ask this for a non-P&L role, they're testing if you think like an owner (meaning: you'll be expected to care about margins more than your team).
Universal Red Flags — Any Role
These aren't questions — they're things to notice during the interview process itself.
| Red Flag | What It Means |
|---|---|
| Interview is with hiring manager only, no team members | They're hiding the team from you. Ask why. |
| They can't tell you the last person's reason for leaving | Non-disclosure or they don't want you to know. |
| "We're like a family" | Emotional manipulation to accept worse conditions. |
| "Fast-paced environment" | Understaffed. Ask about current team size vs open roles. |
| "Wear many hats" | No role clarity. You'll do everyone else's job. |
| Multiple rounds of interviews for L1 role | Indecisive or inflated sense of their own importance. |
| They ask about marital status, kids, or commute | Potential discrimination. Not required to answer. |
| "We work hard and play hard" | Code for "no work-life balance, but free beer on Friday." |
| Can't describe the onboarding process | You'll be thrown into tickets day one with no training. |
| Glassdoor reviews mention micromanagement | Believe them. |
Before you accept
Ask these three questions in your final interview:
- "What does success look like in the first 90 days?" — If they can't articulate it, there's no structure.
- "Can I speak with someone who's been in this role for 6-12 months?" — If no, they're hiding churn.
- "What's one thing you wish you'd known before joining?" — Honest answers reveal the real culture.
