Handshake Senior Software Engineer interview questions

They contacted me after I signed up on the app to represent my current company at a virtual career fair. I thought it was odd they used my work email to contact me- the same email I used to sign up on handshake. After receiving multiple emails from the recruiter about my linked profile being great etc, I decided to interview. The first interview was with hiring manager. I thought it went well. There was nothing technical about it but the next day I got the generic rejection email saying my background was not a good match. I feel like after reviewing me LinkedIn profile and resume they should have know my background was not a good. It felt like a waste of my time. Please stop sending generic rejection emails. When someone interviews at your company, they're taking time they could be using to do something else. The least employers can do is do their own research before contacting candidates and then offer actionable feedback after the interview. The overall experience was rather weird.

I had a phone interview with their recruiter, a phone interview with the hiring manager and online technical challenge with their Lead Software Engineer. Overall the hiring process was fast, about 3 weeks.
