Fortinet interview questions

I was interviewed for the team forticare(SW Application) . After the first online exam which took more than 3 hours , I had an interview with the team including two developers and the hiring manager. They basically repeated the same questions as the online exam, almost spent 1 hour questioning about Indexes in database. And lots of questions about multi threading and Rest Apis. My understanding from the interview with them was that they don’t have a proper team culture. One of the developers was laughing all the time in the interview and the other one was getting mad if you miss something about the questions. And the manager was trying to trick me through the questions. The interview lasted for 2 hours. Such a waste of time. They even didn’t bother to get back to me with a feed back( not a surprise from that kind of people)

I applied it through the internet and replied it via email. One week later I was invited to attend the challenge Forticare Software Developer Hiring test. It took 180 minutes long.
