Applied Materials interview questions

Round 1: It was a coding round. It had 4 programs to be written in notepad. Questions were relatively easy but they expected optimized code as in the next round, questions were asked based on the written code. Round 2: They asked me to describe my Project on a white board and multiple questions on the project internals were asked. Also some general questions on C/C++/OS/DS were asked. Round 3: Again some more technical questions. Round 4: It was a managerial round where I was asked general questions like reason to join Applied Materials, expectations from the company, about the company etc. Also information on company and project was provided. Some prior knowledge about the company helped me as it was also an elimination round. After this they released the offer.

1st round was written test which was decently easily. second was 5mins HR and then 3 on 1 technical round which was kind of tricky. they asked me regarding basics of OS and java. They also asked about my projects.later they gave me pen and paer and asked me to write few java and DS code snippet.
