Actuary interview questions and how to answer them
Actuarial interviews test two things at once: whether you can do the math and whether you can explain it to someone who can't. Most candidates prepare for the first and get caught on the second. Below are the questions you're likely to hear, why they're asked, and what separates a good answer from a forgettable one.
What happens in each round
- 1
Recruiter or HR screen
What happens
Your exam progress, which society you're on, whether you've done VEE, and whether you'll relocate or need sponsorship. Have your exam list ready and say which one you're sitting next.
- 2
Hiring manager interview
What happens
Why this practice area, what you actually did in past roles or internships, and how you handle a model that doesn't reconcile. Expect follow-ups on anything you put on your résumé.
- 3
Technical round or case exercise
What happens
Reasoning through a reserving, pricing or valuation problem out loud. Some teams hand you an Excel file with messy claims data and watch how you clean it and what you check first.
- 4
Team or panel conversation
What happens
Whether you'll be easy to work with during a stressful quarter close or rate filing, and whether you can explain your work to underwriters and finance without talking down to them.
Questions you're likely to get
1.Walk me through how you'd estimate reserves for a line of business.
Why they ask
Reserving is the backbone of property and casualty work. They want to see you know the methods and, more than that, know when to distrust them.
How to answer
- Start with the data: paid and incurred claims arranged into development triangles by accident period
- Name a method like chain ladder and say what it assumes about how claims develop
- Explain when you'd lean on Bornhuetter-Ferguson instead, such as immature years with thin data
- Mention the checks: comparing methods, looking for changes in claims handling or case reserving practice
- Close with how you'd present a range and a selected estimate to management
2.What would you do if your projection model didn't tie to last quarter's results?
Why they ask
Reconciliation eats a big share of an actuary's week. They're checking whether you have a method or just start clicking around.
How to answer
- Break the difference into pieces: data changes, assumption changes, model changes, new business
- Rerun with one change at a time to isolate what moved the number
- Check the input data feed before blaming the model
- Document what you found so the next person doesn't repeat the hunt
3.Explain an actuarial concept to me as if I were an underwriter who hates math.
Why they ask
You'll spend a lot of time with underwriters, product managers and finance teams. Clear explanation is a core part of the job, not a soft extra.
How to answer
- Pick one concept, like IBNR or credibility, and state it in a single plain sentence
- Use an example from their world, such as claims from last winter that haven't been reported yet
- Say why it matters to their decisions, like pricing or renewal terms
- Stop talking once you've made the point
4.Which exams have you passed and what's your plan for the next ones?
Why they ask
Exam progress predicts how quickly you'll be credentialed and how much study support you'll need. They also want to see you've thought about it.
How to answer
- List passed exams and VEE status clearly and in order
- Name the next exam and when you're sitting it, without inventing progress
- Describe your study routine, such as the manual you use and how you schedule practice problems
- If you failed a sitting, say what you changed afterward
5.How would you set a price for a new product with no historical data?
Why they ask
Pricing without data is common at carriers launching new coverage. They want to see you reason from other sources instead of freezing.
How to answer
- Look for proxy data: similar products, industry data, reinsurer studies, bureau rates
- Adjust for known differences in the population or coverage
- Build in a margin for uncertainty and say how you'd size it
- Plan to monitor early experience and revisit the rate
6.Tell me about a time you found an error in someone else's work.
Why they ask
Actuarial work gets peer reviewed constantly. They want to know you catch mistakes and handle it without making it personal.
How to answer
- Describe the error concretely, like a wrong mapping of claims codes or a hardcoded value in a spreadsheet
- Explain how you spotted it and how you confirmed it before raising it
- Say how you told the person and what was fixed
- Mention any control you suggested so it wouldn't happen again
7.What's the difference between a GLM and a simple one-way rating analysis, and when would you use each?
Why they ask
Predictive modeling is standard in pricing teams. They want to see you understand what the model buys you, not just that you can fit one in R.
How to answer
- One-way analysis looks at each rating factor alone and can double count correlated effects
- A GLM adjusts factors for each other at the same time
- Mention choosing a distribution and link function that fit the data, like Poisson for frequency
- Say you'd still use one-way views to sanity check and explain results
8.How do you decide on an assumption, like a mortality or lapse rate, when the data is thin?
Why they ask
Setting assumptions is where actuarial judgment actually lives. They're checking whether you know about credibility and blending.
How to answer
- Start with your own company's experience study
- Blend it with an industry table or benchmark based on how credible your data is
- Explain the effect of the assumption on reserves or pricing with a sensitivity test
- Document the reasoning so auditors and regulators can follow it
9.Why this practice area and not the other ones?
Why they ask
Switching between life, health, pension and property and casualty is expensive once you're on an exam track. They want some sign you'll stay.
How to answer
- Name something concrete about the work that appeals to you, like reserving cycles or long-term projections
- Connect it to something you've already done, even in coursework
- Show you know which society's exams you'll sit
10.Tell me about a time you had a hard deadline and the data wasn't ready.
Why they ask
Quarter close and rate filing deadlines don't move. They want to see how you prioritize and communicate under that pressure.
How to answer
- Set the scene briefly: what was due and what was missing
- Explain what you did with partial data and how you flagged the limits
- Describe who you kept informed and when
- Share what happened and what you'd do differently
11.How comfortable are you in Excel, SQL and a programming language?
Why they ask
Teams vary a lot in how much they code. They need to know where you'll need training and where you can help right away.
How to answer
- Rate yourself honestly for each tool with an example of what you built
- Mention specific things like VBA macros, pivot tables, joins or an R script you wrote
- Say what you're learning next and why
Mistakes that sink good candidates
Overstating your exam progress
They'll check, and it ends the conversation.
Talking only about math and never about who uses your numbers or why
Badmouthing a past manager or a failed exam sitting instead of saying what you learned
Having no questions about the study program, which tells them you haven't thought about the exams
