I applied online. The process took 1 week. I interviewed at Rasa Technologies (Berlin) in Aug 2019
Interview
I received an initial email from the Recruiter to schedule a first call. After the call I was told that I would have another call with the Head of HR, which I did the next day. After that call was successful, I had two more calls the following two days, one with the CEO and one with the CTO.
Each call was professional but laid back, and I felt really comfortable speaking with each person I was interviewed by. The interview process was explained to me in my first interview, and the entire process was really smooth.
I interviewed with Rasa in December 2019. I had a first call with the talent acquisition manager after which I was given the task. I definitely spend some time working on the task. After I sent it back completed I was invited to the next interview during which I explained my solutions into details. I have not heard anything from them after this call even I followed up asking about my application status. As a person who works in recruitment, I believe every candidate is worth a reply.
