I took an online assessment, which consisted of multiple-choice questions and one coding problem. I think I got most questions correct. For the coding problem, I had a solution that worked, but it wasn't fast enough for all test cases, and I ran out of time when optimizing. Two weeks later, I received a call and an email from the recruiter about my availability for an onsite interview. After both calling him back and leaving a voicemail, and also emailing him back, I never heard from him. I tried emailing and calling the next week to follow up again, and still, nothing. I just found it so confusing and unprofessional.

Multiple choice questions about AWS, SQL, and Angular, I believe.
