Pros: Learned a lot about React.

Cons: The few people I talked to (not on my team) said that they were really burnt out.

Pros: I am currently a summer intern at Cisco. In terms of summer internships, I can really say that they have given me real hands-on experience with real responsibility. I came in barely knowing what a network/router was. I feel that I have been able to learn a lot from my co-workers, who are always more than willing to help me whenever I have a problem. My pay is very good compared to what most of my friends are making. If I were to work overtime, they would give me time and a half. It also looks good on a resume.

Cons: Looking around, it seems that people (especially with pending deadlines) put in a lot of overtime and complain that they aren't properly compensated for it. It's also tough because there are some crazy people who will work 80 hours a week, and that will put pressure on everyone else to step it up.

Pros: Smart people, interesting technology. Executives really care about employees.

Cons: Working in big tech always has negatives. The main negative here is enormous code bases and too many people.
