My experience is a match. I received an email from their engineer a week after applying.

There were 2 phone calls and 5 rounds of on-site interviews.

The first round was a pen and paper test, and the rest involved writing algorithms on a whiteboard or paper.

I answered every problem during the interview and the follow-ups.

They were under pressure and really wanted me to join. The engineering team gave me a strong hire decision to move on with the process; however, their HR ghosted me for a month after the initial call. They rejected me with a ridiculous reason.

If you read this:

• The HRs at SMC are totally [REDACTED]. They never show up until you finish the entire interview process.
• They only contact you through LinkedIn messages, which is super unprofessional.
• There is no 401K match.
• They barely reimburse interviewers for on-site interviews (they paid my flight tickets, but not the Airbnb).
• Don't give them your number first until you get the offer, even if it's within the salary range on the job description. Instead of another negotiation phone call, they would rather ask the engineering team to interview more candidates.
