Pros

At this point, I have nothing good to say about this company.

Cons

When interviewing, I was asked straight up if "I was ready to work overtime and on weekends." I was told this was an expectation rather than a potential good effort. When I joined, I was tested vigorously after already getting the job. The tests were confusing and the answers were not obvious. The documentation was unreadable. This was after an application test and four rounds of interviews. When I worked as hard as possible, asked a weekly check-in call to keep my questions from being a problem, and worked late, I was told "I was working too hard" and that my work was below standard. When I got married, management told me that needing to take an appointment for my wedding was inconveniencing the business. I was fired while celebrating a religious holiday. No reason given. I had to beg to get the bonus that I earned as part of my severance package. After I was let go, my manager left the team entirely. The CEO and management pretends that they are kind people who support their workers. Unfortunately 90% of the company is clouded by anger issues, mired in personal attacks, and struggling with feedback that is unclear and conflicting. I am unclear how this company has gotten so many awards for diversity. I only saw minorities let go during my time at the company. The few people who are actually good at their job are fighting constantly to keep up with the environment. I'm shocked they even have a product that works given the company's disorganization and culture.
