Lam Research Mechanical Engineering interview questions

It was through campus placement, very long , wearing, and exhausting interviewing process. At first there was an aptitude test in the campus itself, followed by a ftf interview round at companies office a week later. The ftf interview consisted of 2 round the first one was technical ( abt your projects and basics of your subject of choice) which lasted for 60- 90 mins and then if you clear through that the second round was technical/Hr(just to check your attitude and dedication towards work) which also lasted for 90-120 mins. Generally they send a mail by 2-3 weeks, But sometimes keeps your profile in waiting for 3-4 months( in my case). Then there was a telephone interview with the manger for about 60 -75 mins (about the projects you have done and basic questions from preferred subject). At last after 4-5 months got the offer letter. During all the interview process...the interviewers where polite and friendly and that the base of the company itself. It all depends on you.
