CarGurus Software Engineer Co-Op interview questions

After a brief 20 min recruiter phone call, I was invited for a zoom technical interview. The interview consisted of 3 rounds of 45 minutes each with different engineers from the team I am supposed to join. I was nervous at first, but the engineers were all nice and welcoming. Each interview started with a small enjoyable conversation about the job, nothing felt rushed. The first problem was an algorithmic question concerning the addition of two polynomials. The two other rounds were much more interesting. The problems were actual challenges that the company was working on; I enjoyed this part thoroughly since the solving process felt more like a conversation than an exam and the problems made me interested in joining the company even more
