Round 1: It was a coding round. It had 4 programs to be written in notepad. The 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 whiteboard, 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 the reason to join Applied Materials, expectations from the company, and about the company, etc. Also, information on the 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.
