I applied online. The process took 2 months. I interviewed at ZEISS Group (Munich, Bavaria) in May 2018
Interview
Telephonic interview from HR, followed by personal interview. They have very interesting projects. Questions were of average diffculty level on the topic of the applied position. Wouldn't recommend for people who are looking to end up in a job within a few months. They application process takes very very long time.
Interview questions [1]
Question 1
Completely inappropriate handling of the applicant. Very bad communication between HR and Tech lead. Received a time slot for interview but actual interview took place on another day without prior notice.
