I really enjoyed the process even though I didn't get an offer.

The recruiters and the technical interviewers were so kind and smart and talked to me at the same level. I felt like they really wanted my best and didn't try to fail me. Also, I constantly got honest feedback from them and that helped me to gain confidence for the next stages.

To my surprise, instead of a generic email, they actually phoned me to tell me that I didn't pass, but also they enjoyed meeting and interviewing me and to not hesitate to apply again in the future.

The topics included system design and real-world problems.
