The interview process usually depends on the role and seniority; however, you can expect the following on a Liberty Mutual Insurance software engineer interview:

Recruiter/Hiring Manager Call Screening

If your CV is among the shortlisted few, a recruiter from the Liberty Mutual Talent Acquisition Team will contact you and verify key details like your experiences and skill level. Behavioral questions may also be part of the screening process.

Sometimes, the Liberty Mutual hiring manager stays present during the screening round to answer your queries about the role and the company itself. They may also indulge in surface-level technical and behavioral discussions.

The whole recruiter call should take about 30 minutes.

Behavioral Interview Rounds

After successfully navigating the recruiter round, you will be invited for two 1-hour behavioral interviews. These interviews typically focus on STAR (Situation, Task, Action, and Result) questions. You will be asked to describe your past projects, explain your teamwork and conflict-resolution skills, and respond to queries about your strengths, weaknesses, and reasons for wanting to join Liberty Mutual.

Technical Interview

Following the behavioral interviews, the next step involves a technical interview that lasts around one hour. You’ll be expected to solve technical questions that cover easy to medium-level LeetCode problems, including coding and debugging exercises. Questions can span core engineering concepts focusing on problem-solving and coding efficiency and potentially some questions about design patterns or technologies relevant to the role.

Onsite Interview Rounds

Once you’ve passed the previous rounds, you may be invited to attend an on-site interview loop. This usually includes interviews with panels of engineers and a hiring manager, which may involve whiteboard coding sessions and in-depth technical questions. Toward the end of the session, behavioral questions are also asked to gauge your fit within the team and company culture.

By preparing thoroughly for each stage of the process, you can enhance your chances of success and make a strong impression on the interviewers at Liberty Mutual Insurance.
