Good interview process, only asked relevant questions and not to inverse a binary tree. The process took a bit longer than necessary though. Adding extra words so glassdoor will take the review

Was straight forward, multiple round interviews. First a technical one followed by a coding test, later an HR one, and finally a meeting with the CEO (which was a great experience). People were very nice. The only thing that was not the best was the the final steps of getting the contract took a while.
