Pros
The health benefit is probably the best part (only for individuals though). The other good thing is the location - Cambridge is the place to be. CEO is super friendly and good to talk with. Not sure if the concerns get addressed though after speaking with CEO.
Cons
One of the previous reviews mentions about HR having great power. Which is true. I have not worked in a place where HR has been given so much power. Almost feel like a school child being reprimanded at each step. So much power that at one point HR asked everyone not to send mass emails to the company wide email list , but send it to them instead and then if they seem to think that it is an email worthy to be sent to the entire company, they will send on your behalf - this is so ridiculous!!!
Some of the engineering leads act so high and mighty - make everyone else feel like minions.
Culture is not transparent. Things are never done on time.
