I applied online and was contacted by a recruiter shortly after applying. After this, the recruiter was very hard to reach. After the recruiter, I had a total of four interviews: one hiring manager interview, two technical discussions, and one coding round. The recruiter did a horrible job in scheduling these interviews. I had given him my availability for a week out and got them scheduled. The recruiter then moved my already scheduled final round to one week earlier, with only one day's notice, meaning I received the notification that my final round was moved to the following day of receiving that notification. This is absolutely unprofessional and got in the way of my preparation time.
