Fi Software Engineer interview questions

1 screening, 1 technical interview, onsite for 3 hours. After this process the offer is sent by team leads. It's standard technical interviews but has some emphasis on the product.

Recruiter reached out and set up a time for a technical screen. A couple of hours before the interview, recruiter sent an email saying the team is busy with wrapping up on a feature and needs to reschedule. Replying with available slots was unanswered. Sending another email a few days later was responded with a generic rejection email. Unprofessional.
