Informatica Sr. Software Engineer interview questions

I have known Informatica to be a good place to work so when I saw a job posting at glassdoor I applied. Few days later a person named Srinivas claiming to be HR at informitica called and was very rude. He asked why people like you(with consultancy background) apply for jobs posted by reputed companies like us.

Recruiter contacted me on Linkedin. Briefed me about the position. It was a backend technical role and very interesting. Setup 45min phone screen. Was interviewed by someone who was a Software Engineer converted from being a QA engineer. She straightaway started with question without introducing herself or asking about me. It seemed like she was reading a script of question and answer. Would consider her as slightly junior for conducting a Senior Software Engineer position interview. Asked two LeetCode Medium question in 45mins. She gave hints wherever necessary. Got a generic rejection email. Few days later after the rejection email, i received 2nd phonescreen request from the Principal Recruiter. This was however for UI position. I was confused because I had interviewed for a backend position and had gotten a rejection email. Got on a phone call with the recruiter and realized that 1st phone interviewer had actually passed me on the interview and forwarded me for 2nd phonescreen. However, the position that i had initially interviewed for got filled in 2 days, hence i received a rejection email. This was a bummer and would have expect the process to be more transparent and recruiters realize what is going on.
