Lam Research interview questions

Interview was from easy to moderate and there was a online assessment of 45 questions and shortlisted candidates are eligible for the physical interview in college campus for the interview

Interview itself was mostly fine but the logistics and lack of follow-up from the recruiters after the interview were frustrating. They were excited for my application prior to the interview and seemed very interested during it, so I was disappointed that the recruiters ghosted me afterwards. Plus, they had to pull in two substitute interviewers in a row due to logistics issues. Perhaps because of this, it felt like the interviewer did not review my credentials at all, since they asked very basic questions that were rather insulting considering my skillset. Please consider that your prospective hires may be future customers. This experience has tainted my good perception of the company. How will I know that they will handle my future projects with professionalism if this is how they treat other people?
