Tough place to work

Pros

Good pay and benefits, occasional amenities

Cons

They don't really pay that much attention to the people that work there or their career trajectories and they expect a lot. I interviewed for a job with a very specific tech stack - passed all the rounds of interviews, At each step I'd ask to confirm that the role was for the tech stack I was interested in - At every step the interviewer either passes the buck or confirms that the job description is correct. I get there on the first day and it's an entirely different tech stack/role. It was really tough to manage! Ended up getting laid off eventually in an unceremonious way with other people. The guy who took my key card was the same dude who lied to me in my final round interview.

Pros

They offer standard employee benefit including health insurance and 401K.

Cons

A lot of change in the management. It seems to be not very well organized. No transparency and no clarity on goals. No RSUs and compensation is not very competitive.

Pros

I want to give zero star but 1 is the smallest

Cons

Terrible! I worked in Boston office and the cultural is toxic. Working hour is much longer than the industry. People sometime need to work overtime that is due to senior management bad schedule. Wouldn’t get any appreciate and no overtime paid bonus. Salary is lower than the industry average but highly demand on the work. 5 days on site work. No flexibility. Stay as far as possible!
