I was referred to Arista through a friend. A recruiter called me about a day after that. The interview was scheduled in two days. There was no phone interview, as I was already in Bangalore and they asked me to come in for a face-to-face interview. I was told it would take no more than half a day.

I reached the office at around 9 AM.

• The first round was a coding round. The good thing is they provided a laptop and asked me to code on it. The questions covered basic problem-solving, algorithms, and some language fundamentals.
• The second round was a problem-solving + technical round. I was asked to design a real-world problem, write header files for the interfaces, and explain how it would be implemented. This round was conducted by a couple of directors of engineering at Arista Bangalore.

After that, I had informal discussions with another manager and lunch. The entire process was completed by 2 PM.

I was selected and received an offer within two weeks.

Create a module for a real-world problem. Write down the interfaces of that module and how you think it can be implemented efficiently.
