The Interview process was similar to what I have read on glassdoor.
Firstly, they sent me an email to ask for choosing an appointment. After that, they sent me an email to ask me for completing an application, personality assessment, etc. ( there were 4 timed sections and 2 untimed sections)
Secondly, at the on-site interview, I was sent to a lab to complete an aptitude test. This test included 3 sections: detecting sequential patterns, determining spatial relationship, testing math aptitude. Did expect to finish this aptitude test in a limited time.
Thirdly, after the aptitude test, I was called for a Skype interview with hiring manager ( I guess!! ), it was just traditional interview ( asking about why I wanted to work for this company, etc. ). After that was an interview with senior engineer, all questions were just about my background, courses, projects, etc.
I am wondering if they are seriously hiring or not. Because, you will see many other people like you coming into their lab to do the same aptitude test and this happens very often during a year or even a month!!!
I did not expect to pass the interview, but still accepted the appointment to get there just to have an interview with them so that I could get some experience for other future interviews.
