LogRhythm Software Engineer interview questions

I only got to the HR phone screen, but the recruiter I spoke with was very inconsiderate. He was very disengaged through the whole call, but that wasn't the worst of it. He warned me at the end that he was going on vacation right after our call and that I should follow up in a week (isn't that your job?). Sure enough, a week went by and I heard nothing. So I reached out. Guess what? Still heard nothing. I sent a second followup and I heard nothing again for yet another week. Finally, after 2 - 3 whole weeks in total, I received a boilerplate email that said "we have decided not to proceed with your candidacy for the current opening" because "there are other candidates that align more effectively with the requirements". I am not upset about the rejection, but rather the ignorance that this company provides to candidates they don't deem worthy anymore.
