The failure to respect women in the company is blatant, but management won't acknowledge the issue. There's also a serious lack of diversity. All of management is white men, and they make decisions in the stereotypical way that you hope doesn't exist anymore. The wage gap between men and women is disappointing, and wages across the board are below market rate.
The focus of the company is getting work done fast to make a quick buck, instead of building out a great, quality product. Interns are used for free/cheap immediate labor, instead of being trained properly to be better full time employees in the future. Basically every task is get it done now, fast, and shove it out the door before it breaks.
The lack of maturity on the part of some key players in management is disappointing and unprofessional. Decisions should be made for the good of the company, not based on your feelings.
Basically every bad thing about tech startups that you hear about, is here.
