Interview process was rather smooth and hiring manager was pretty friendly. Mainly asked about what is written on the Resume. They might throw you a couple of scenario questions and ask you to explain what you will do or how you will react if such situations arises.
The process took 2 months. I interviewed at Heraeus
Interview
HR reached out and was very responsive at first. Got to talk to the hiring manager for an hour in a week, told me that there will be 4 rounds of follow up since they are a German company. Sent a survey asking for references, and heard absolutely nothing after that. Followed up via email twice and heard nothing back.
