I can say it was not the best interview experience I had (the HR is not at all flexible on your start date). The manager was rude and didn't let me to finish my answer. He tried to downgrade my engineering background and work experience by asking meaningless questions. At the very end they went through some behavioral (STAR interview format) questions.

I didn't apply for any job with them, they saw my profile and initiated communication. In person interview went very unprofessional hr showed up 10mins late , technical was flat. Interviewers were not prepared at all. They were going through the resume for the first time. They were more interested in what my company was doing, I doubt if there was ever even position open. Low energy levels of the interviewers.
