It was simple and three rounds of interview. One with Engineering manger and one with CIO, and lastly with HR manager. And they sent me an coding assessment as well.

Extremely long, 6 steps and long wait response times. At the end I rejected the offer due this delay in the process (that took almost 2 months). Also, the role that the headhunter said was a bit different of the real role (which included more tasks than the offered)

The first meeting was a 30 minutes virtual meeting. It was about getting to know each other and talk about your background. The second meeting was a coding challenge, which takes about 1 hour. Nothing special, just to demonstrate you worked with C++ before. The third meeting was with HR, to discuss things like salary, working hours etc.
