Angi Software Engineer Android interview questions

I applied via glassdoor. Was contacted by a recruiter and we setup the initial call. Everything went well and I was asked to scheduled a technical phone screen. But, then the recruiter left and my application was in limbo for 3-4 days. Albeit, a technical interview was scheduled by another recruiter. The interview invite indicated - in writing - that the interview question is going to be a variation of two sum problem. The interviewer in the interview ended up asking a hard leetcode question. I could solve a single iteration of the problem and struggled in the rest. The interviewer did not show any intention of helping me during the whole interview process. Got a reject next morning.
