LOVE THE COFFEE

Pros

I love the coffee there seriously. I would wake up every week day and take the train at 7am and get a black coffee with vanilla flavouring, very nice! They also used to have a white board mirror and a wise old guy.

Cons

The old boss was sometimes very moody.

Interesting problems, real science, nice colleagues

Cons

Insufficient job security, too much pressure that is grounded in commercial interests rather than technical milestones.
