There were 4 rounds in total. The online test was the first.

It consisted of 3 sections:

• Section 1: Aptitude and logical reasoning
• Section 2: Basics of C and data structures
• Section 3: Technical - Digital electronics and basic electronics

Then, in the first interview, they asked about projects and research I had done, and the interviewer asked questions on them.

The second interview was completely technical. Topics included VHDL coding, setup time, hold time, IIR and FIR filters, digital electronics, and questions on semiconductor devices.

The final round was HR. It was easy with normal questions, such as "Why should we hire you?", "Your hobbies?", and "Where do you see yourself in 5 years?"

They were given a circuit and delays and asked to calculate the setup and hold times for proper functioning.
