Arm interview questions

Very strange interview process, which lacked professionalism and depicted lack of communication between teams in Arm (may be because of Nvidia acquisition, I don't know). I firstly got interviewed for a position in the OSS team, but that position got filled and Arm decided to interview me for other positions. I did well, And the HR department contacted me for salary negotiations. We agreed on a base salary and I asked Arm to send a written offer letter to me. The next day I got the rejection email from Arm. Of course, Arm is a great company but I've had better experiences with much smaller companies.
