Arista Networks

They have some intelligent people working there that you can learn a lot from.

I was in the Vancouver office and I have no shortage of complaints about the company. Fortunately, I'm currently at a big-4 company, so I have some baseline to compare to.

• The environment was toxic. There were often huddled discussions amongst my coworkers badmouthing other employees/managers. Few people interacted positively with each other. Everyone was in cliques and didn't really try to make interns feel welcome.
• The work was terrible. They gave an intern, with almost no good understanding of the large codebase, the task of merging two branches that had been disjoint for 1 year and a half. After, inevitably, receiving a few hundred files with merge conflicts, people refused to help me (including my mentor) citing business. I was left to figure it out on my own and chase people to help me.
• The organization is filled with people who are there to have a job. There is no motivation or drive or belief in the mission of the company.
• The tech is so unnecessarily complicated that you have to understand everything before being able to contribute to a single portion of it. It seems like poor organization.
• You cannot rely on the code to work. I often had arbitrary build errors -- which I would then find were due to something completely independent of my change. The hardware often breaks/is buggy as well.

Overall a terrible place to intern. I didn't learn anything, didn't enjoy my time, and was almost completely deterred from working in CS. Seriously, if you're in Vancouver, there are tons of better companies to go for.

Set a baseline for how interns are treated. Ensure that they're not given the worst/tedious projects (e.g., merging two branches that were distinct for a year). Ensure that they're treated properly and enjoy themselves.
