Applied Materials interview questions

I was contacted by the hiring manager for a first tech round. It was basic string and array problems. At the end of the phone call I was told they would like to fly me for an onsite . During my onsite I had 4 interviews with developers from different teams. All of them were well experienced and had a sound knowldege on c/c++. I was mostly tested on c and c++. I was tested on algo problems and writing test cases. It was a good experience altogether
