OppFi Software Engineer interview questions

2 rounds in total, all the interviewers are very nice, the office looks good too. Coding part was not that hard, but the OOD part was very difficult for me(non-native speaker) personally.

Applied online and was contacted by who I assumed to be a technical recruiter at the company. Scheduled a 30-minute phone call to talk about the role. On the call, the recruiter described the role as if I had not done any prior research on the company, the role, etc. and asked whether or not I had experiences using x or y technologies that are clearly described on my resume. As the call was ending early, I had to ask the interviewer who seemed eager to jump off the call, if she had time to answer a few questions. I had basic questions about the relationship between product/engineering, basic business model, etc. of which she did not have enough information to answer - 'I don't know, I'm just a HR rep'. All three of my questions went unanswered. She ended the call by letting me know that she would pass along my information to the hiring manager and I would hear from the hiring manager for next steps. Got an automated rejection email from the same interviewer a couple of days later - no word from the hiring manager. This interview should be conducted by somebody more involved and informed with the technical operations much less the basic business model of the company. What a waste of time for the candidate. It's obvious that the representative hadn't spent the time looking over my resume prior.
