I applied through a recruiter. The process took 3 weeks. I interviewed at Arista Networks (Bengaluru) in Mar 2022
Interview
Contacted by a recruiter. The interview process went on for 3 weeks. There were 3 rounds of interviews, first one was for DS and algo, the second with the hiring manager, and the third with both the hiring manager and the director.
All the interviewers started with some questions on C++ followed by DS/design question. The interviewers are really friendly and the interviews felt like a discussion. The recruiters took around 4-5 days to respond after each round.
Interview questions [1]
Question 1
1. Modify stack to get the average of top n numbers
2. Get all anagrams of a string from the dictionary
3. Design a phone directory to search contacts with first/middle/last names and get the most frequently used contacts
4. Search for duplicate lines in a log file with very long lines.

Interview
Pros:
Great initial approach – the recruiter thoroughly checked my GitHub profile and projects before the interview, which is very uncommon and shows they do their homework.
Cons:
A major mismatch between the job description ("Software Engineer C++") and the actual interview reality. The technical stage on CoderPad strictly tests bare-metal C98 skills: raw pointers, manual bitwise operations, and packing bytes into 64-bit integers. If you are accustomed to modern C++ (RAII, templates, safe memory management), this will feel like a massive step backward. Additionally, the time expectations for live low-level bit-shifting were unrealistic, to the point where the interviewer started solving the task themselves.
Interview was kind and not stressful, just minor mismatch of naming
Pretty good, not too complicated, was comfortable. Mostly LC questions, and was easy enough that you should be able to do it after doing NC150. good luck for the interview!
Starts with online test, then three rounds of technical interviews follow.
Not a lot of discussion, just go straight to the technical challenges which have to be solved in time
