I applied through an employee referral. The scheduling was done in a couple of weeks but the whole process took a bit longer than average due to my availability.

Everything went smoothly without major issues. The recruiter was very responsive and helpful.

Standard software engineer questions such as algorithms and data optimization. However, since my job is related to hardware as well, there are some questions regarding hardware design and timing problems, e.g. hold time, set-up time, and resolving timing violation.
