LinkedIn Sr. Software Engineer interview questions

The interview process consists of one phone interview and 2 on sites. I had a positive experience interviewing with LinkedIn. I looked over the reviews here before I went. Some criticized the working environment and the interview process, but I experienced the opposite. Everyone I met was friendly, smart and they spoke highly of their team environment. The building/conference rooms where I interviewed in were clean and updated. The hr person I worked with was very helpful and communicated well. So maybe they saw the reviews here and made improvements? They asked a few harder questions, which I see as a good sign because you can expect your future coworkers to be competent. I think the company has great unrealized potentials still, and I like the director and the hiring team a lot, so I ended up choosing them over another more competitive offer.

I applied to the position on their website and I got a phone interview which lasted for 45 mins. It was completely Java. I was grilled with questions including thread safe class, hashcode() & equals(), design of website etc.
