My interviews were with a Director and then a team member, and the whole thing covered a blend of topics. We spent time on basic OOP concepts, some DevOps-related questions, and even a database command where I had to write a query. Along with that, there were behavioral questions about how I handle conflict and how I’d describe my interests in a way that would get the team engaged.

What stuck with me most was how supportive the tone was. At one point the interviewer actually stopped me and said my answer was good, which gave me a real confidence boost. I genuinely liked the culture and what the team talked about, including details like not working on Fridays, and I sent a thank-you email afterward. Even though I felt like a strong match and was excited, I was later told they moved forward with someone else. It ended professionally, but I left disappointed because the process felt so respectful and still didn’t turn into an offer.
