I had a very good talk with HR and failed after that. We talked about very thing like work experiences, why I want to migrate to Germany, my salary expectation. It was my first English conversation and I feel my rejecting reason was my bad English

The process was very clear and straightforward, 1- HR 2- technical 3-coding challenge 4- deep dive into technical topics mostly based on the coding challenge 5- team fit and culture fit 6- discussing the offer From the get-go whoever i met they were super nice and super professional, giving clear and constructive feedback, very clear about the team and company instructions, they were very patient with whatever questions or miscommunication from my side. The level of knowledge of all the engineers was very high and i got to learn so much from them.
