I applied online. The process took 1 week. I interviewed at Arista Networks (Dublin, Dublin)
Interview
HR contacted me after my application, asked if I had any contacts with other HRs in the company (?), and invited me to a coding assessment. I needed to score 100% to be moved to the next stage. The next stage was life coding. The first interviewer said he wasn't the right person to conduct the interview with Python, and HR rescheduled the interview. The second interviewer seemed to be in a hurry. He didn't give me any time to think and started explaining the solution immediately. This being my first life coding interview, needless to say, I failed miserably. At the end of the interview, the interviewer asked if I had any questions, but interrupted me when I started asking them, said that I should ask HR and ended the call. The rejection came only when I followed up after two weeks. Overall the process seemed messy and uncoordinated. Very fast though, all interview stages ended within a week.

Interview
The technical interview process went smoothly. It consists of connecting to their test environment via ssh and ussing the terminal to navigate between files, compile your work and execute it. The interviewers were very pleasant people and are very patient with you and help you along they way by both pointing in the right direction, and giving you tips if they deem so. I was asked to complete two simple hackerrank style questions, It did not take me the listed interview length time to complete them and finish the interview.

Interview
The online assessment was a string-based question, but I don't recall the specifics. After passing the OA, the first round of technical interviews was conducted using CoderPad, requiring candidates to choose one of three programming languages: C, C++, or Java. The interview consists of solving three problems within 90 minutes, all of which are basic problems at the Leetcode Easy difficulty level. Previously, I had been using Python to practice problems for six months to improve my speed, so I spent a week reviewing C++ before the interview. However, the results of the last-minute review were not as effective as consistent practice. I wasted a lot of time on basic syntax issues and compiling and debugging C++ code using CoderPad, resulting in only completing two questions within the 90-minute timeframe. The interviewer was very kind and could tell I was not proficient in C++, so he patiently helped me review C++ syntax.

Compare two version numbers, which was also a string manipulation problem.

Interview
OA followed by a live coding interview, the interviewer had such a strong foreign accent, that I could not understand half of what he was saying even after asking him to repeat. This hindered my Interview as I was not entirely sure what he wanted me to do as I couldn't understand him. Wish they would use people that speak clear Engish in English speaking countries.
