Poorly run startup

Pros

Good startup perks such as catered lunch, unlimited PTO and flexible with working from home (dependent upon your position).

Cons

Company culture stems from the top down and with abrasive and negative people at the top, the entire organization is affected. Upper management is great at hiring talented and smart people, however they don’t allow those people autonomy and the ability to do their jobs as they are overly involved and instill fear in their team. The CEO knows no boundaries and does not respect the opinions of his team. Company wide emails at considerably late hours in the evening shows a lack of respect for employees and their personal lives. Startups are hard work, there’s no question. But hard work does not have to include hostility and fear. You’ll make a good salary if you join this company, but it comes at a cost.

Pros

Lunch for 3 days a week (not for the San Jose building).

Cons

Notice all the good reviews here are made by new accounts (worked here for less than 1 year), written in a strange bullet point or list format, and suspiciously all in the same word count. They'll probably switch it up after seeing this post. People who have interviewed here have asked employees why the Glassdoor reviews are so poor and the HR department is trying to prevent that. Read the bad reviews if you want an honest take of the company.

As toxic as it gets

Pros

A few good people unfortunately feeling trapped.

Cons

Toxic/ negative environment, backstabbing, no trust, no management know-how, CEO doesn’t have a clue, wastefulness, wishy-washy, lazy managers with poor communication skills/ emotional control. Good hires soon leave.
