J'ai postulé via un recruteur. Le processus a pris 3 jours. J'ai passé un entretien chez Arista Networks (Bengaluru) en avr. 2021
Entretien
Recruiter contacted me and 3 rounds of interview were held. All rounds were held virtually. I was made to ssh to their server and vim was used for coding. Interviewers were very nice and helpful.
Questions d'entretien [2]
Question 1
Round 1:
Few output questions related to static variables, format of printf function
Coding Question:
Q1: Given a very large number, which cannot be stored in usual data types. How will you store it and add one to it?
Q2: Given an sorted array of numbers, find the missing number in less than O(n)
11,12,14,15,16,17
O/P 13
Round 2 and 3 were combined together and it was 1.5 hr long:
O/P question related to pointers, static variables
Pass by value/reference, pointer arithmetic (know your pointers throughly)
How to design free function of your own?
How to count all objects instantiated by a class?
Runtime polymorphism in c++
Design phone book: search by name, phone number and print 10 most dialled numbers
Why BST cannot be used?
Comparison between bst and trie
Benefits of trie over bst except search optimisation
Time complexity in bst

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

Reached round 3 out of 4 planned, one was coding task, two live coding sessions. Linux development background was highly expected. Performance optimized approach was tested, specially oriented for hardware with lots of resources. I had a problem to properly understand reqruiting person during round 3, voice was not clear for me.
Questions d'entretien [1]
Question 1
List implementation, bits counting, tre traversal.

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!
