I had an extremely positive interview experience at WEX. After submitting a resume and cover letter, I was invited for an on-site 1:1 interview with the hiring manager. This 30-minute interview consisted of traditional interview questions (tell me about yourself, why WEX, what do you know about WEX, etc) as well as a handful of behavioral questions (tell me about a stressful situation, tell me about a project that didn't go well, etc). The next round was with ~6 people and lasted 1 hour. The interviewers represented various departments I'd be collaborating with and were of different levels within the company. Again, the questions were largely behavioral. I'd suggest reflecting on challenging projects (and practice articulating how you solved the problem and what you learned) before interviewing. The rest of my interview time was for me to ask questions. I left the experience feeling really excited about the position and the people I met with. It's clear WEX employees are enthusiastic about their work and the direction of the company. Overall, I was very impressed.
