Business Outlook

Pros

Most people at this company are kind and helpful. Compensation is truly competitive. Autonomy. I believe in the product and science behind it.

Cons

There was no official HR department - I truly believe that if we had an HR department, feelings and actions would not have escalated to where they did.
