Heliolytics interview questions

I had an Initial interview with the hr, then I had 2 rounds of interviews, first with the team and then managers. It wasn't hard, mostly about my background and skills.

Had 4 rounds of interview. The first 3 was with the HR and few other engineers and the last round was with the engineering team including the co-founder. I had a great experience for the first 3 rounds but I hate the last round because the co-founder seems does not care about the interview at all
