The interview process wasn't professional. I was contacted about the interviews way after working hours and on weekends. There were 4 rounds of interviews, and after all that they disappeared for a few weeks even though they promised to get back to me with their decision after a few days. After dedicating weeks of my time to their interviews and task I only got the message that basically said "We went with a more experienced candidate, but you were great" as if they didn't know my experience before all the stages of interviewing (so the feedback had zero value). Overall - wouldn't go through that again.
