Software Engineer Interview

Anonymous Employee
San Jose, CA

I applied online and the process took 2 weeks - interviewed at Arista Networks in April 2014.

Interview Details – Applied online and was contacted within 3 days by a Software Engineer.

What I loved about the process was that there was ZERO HR correspondence. The interviewer's were the ones directly emailing me and that was great.

The conversation was casual, and I was honest from my end which really helped. Interviewed with 2 more Software Engineers from the team and finally with the VP for the offer. Great, quick responses!

Interview Question – No technical questions   Answer Question

Negotiation Details – No negotiations. Great Offer.

Average Interview

Software Engineer Interview

Anonymous Interview Candidate

I applied online and interviewed at Arista Networks.

Interview Details – Worst Experience in all of the interviews I have attended.

First about me. I had graduated 4 years ago and I had quite some experience in the industry.
The first round is you have to ssh into thier system and the interviewer had 2 questions for me. Some clever way of linked List printing and another clever way of tree traversal.
I nailed both these questions, all the tests passed and The interviewer was all praise for me.
He told me that I was to be ready for the next round, Congratulations and all.

Now comes the interesting part.

The second interviewer asks me to send my Degree Transcripts <wth? I'm not a fresher> Ok, I send it.
My GPA at masters is 3.5/4 and my Undergrad was 8/10.
He looks at those and he sends me a reject email without even interviewing me.
First of all, I'm not a fresher, and if at all I'm hired, Arista gets to employ someone who obviously has more than academic knowledge.

So mean people, and heavy headed people. They could have told me that there is a GPA cut off even for non-freshers so that I could have better used my time, bad interview process.

Interview Question – Linkedlist intelligent printing.   Answer Question

Software Intern Interview

Anonymous Interview Candidate

Interviewed at Arista Networks

Interview Details – I applied for an intern position over the summer. I've got not complaints about anything leading up to the interview process - the people on the other side of the emails seemed nice, and organized my interview very professionally. Then came the interview... at which point I was told to implement a rather easy question - just finding the missing number in an array. The problem was so basic, but I had some serious trouble because I was told to use a Mac (at which point some of the Windows hot keys I accidentally pressed closed the text editor), and I was told to use eMacs... the worst texteditor in existence (imho)

Interview Question – Find the missing number in an array of adjacent, increasing numbers in logarithmic time.   Answer Question

Summer Intern Interview

Anonymous Interview Candidate

I applied through college or university and the process took 5 days - interviewed at Arista Networks.

Interview Details – Ask questions about find the successor of a node in the binary search tree, find the missing number in the array, using vim and gcc to compile, using gdb to debugger. Can only use C language. The most import thing in the interview is to keep sober, the problem is not hard, but need to be careful to solve it.

Interview Question – Using C, not used it for a long time   Answer Question

Summer Intern Interview

Anonymous Employee

I applied through college or university and interviewed at Arista Networks.

Interview Details – I had a 30 min phone interview, and it can be divided into three sections:
First, the interviewer asked some questions about my resume (like course, projects).
Then, I was told to ssh on their server and write my answer (c code) to a programming question. After finished code writing, compile and test with sample input.
At last, the interviewer asked me some basic network knowledge, such as tools and protocol detail.

Interview Question – I don't have much experience with C. So I spend more time thinking about implementation.   View Answer

Difficult Interview

Software Engineer Interview

Software Engineer
Remote, OR

I applied through an employee referral and the process took a day - interviewed at Arista Networks in February 2014.

Interview Details – Compared with other companies, the company seems to focus a lot on the language details of C, instead of more algorithmic questions. In general, I do not like the interview process. I guess I will not enjoy working on the details there even if I am accepted.

Interview Question – There are a few questions on the details of C.
1' The role of fflush to flush out the strings.
2' A macro that computes a size_t number. Putting in a loop, it casts -1 to a size_t number, making the loop impossible to start.
3' Sudoku solver
4' Design a generic stack class.
