Applied online, followed by a recruiter call, a coding interview, and a system design interview.

Everyone I talked to was great, and generally, I would rate the overall experience positive.

The reason I gave it a neutral rating is because I received a simple email, instead of a phone call, informing me that I didn't get the job because they had filled the role.

This may be personal preference, but when I've completed a full interview loop, I expect to receive a phone call.
