The role's qualifications specified 3 years of experience, but I was invited to interview regardless.

The recruiter provided a timeline that included a "phone interview" and then "onsite interviews". However, after applying, I was invited to a 45-minute technical interview over Zoom. I signed an NDA, which was mostly about protecting trade secrets of the company I was currently employed at during the interview process.

I was interviewed by a software engineer at the company on a DSA problem. They did not invite me back nor provide feedback after the interview.
