Gusto Software Engineer interview questions

I applied online for a "Software Engineer" role. A Gusto recruiter reached out to me and I sent him a link to the rec/position I applied for. We had a very generic conversation and scheduled a time for the technical coding portion which was 1-hour with an engineer. The coding session was fine; I added the problem below. A day or so later I received an email from the Gusto recruiter saying I would not be moving forward in the process for "Senior Software Engineer." I did NOT apply for that position, but the Gusto recruiter obviously lied about it because recruiters get more money for filling higher level interviews and positions. I was really annoyed. From now on whenever a recruiter sets up an interview I make sure to confirm the title of the position with the engineer during the interview before I start doing any coding.

Only had a recruiter screen call but was pretty much a complete waste of time. The recruiter talked about himself during most of the interview. I barely could get a word in. When he did asked me about myself, basically asked me nothing he couldn't get from my resume. He asked me if I had experience in system design in front end components, which I did, but he seems to be hung up on what Gusto calls it as their system design team, in which my company calls as the shared UX team. Tried to explain to him the work is the same except the difference in the team name. He seems either not to understand or just was too into himself talking than to listen. He talked so much about himself that there wasn't any time left for me to ask questions at the end. The kicker is the rejection email that partly states that "we know you may desire further assessment of your interview performance but we cannot provide any feedback regarding interview outcomes", which is a joke for only a recruiter round, but also no thank you, I don't really "desire" any feedback from this recruiter or the company.
