Behavioral Coding
So, there were two rounds. The first round had some basic behavioral questions like 'tell me about yourself' and 'why OSIsoft'. Then there was a coding challenge, a simple recursive method. The second round was with the team manager, and they asked about the conceptual difference between two programming languages.

Technical Coding Behavioral
I was first contacted via email to send in a code sample and some answers. Then I had a technical phone interview where the interviewer gave positive feedback. We did pair coding and it went well. After two weeks of no response, I followed up and they scheduled another technical phone interview. We did pair coding again and got more positive feedback. Two weeks later, I followed up again and got an invitation for an on-site interview. This included a 30-minute HR chat, a 1-hour resume and skills interview where they explained the PI system architecture, and a 1-hour technical interview with pure technical questions that I answered well. The interviewers were nice, and the job and company seemed great. I was told I'd hear back in two weeks but got rejected. Research on LinkedIn suggests they only hire from top universities, which might be the reason for rejection. I wish recruiters wouldn't waste students' time if they have such strict hiring policies. It's unfair, especially considering some students can't afford top university fees. Despite the nice people, they should reconsider their hiring policies. The whole process felt like a waste of my time.
