Pros
This is a decent first job in tech where you would at least not pick up too many bad habits in terms of day to day work. Flat organizational structure is good for creating opportunities to advance. The product itself is useful so that is worth getting up in the morning for.
Cons
There is a passive-aggressive company culture where co-workers are kind to your face but talk bad behind your back to supervisors. People who are more established may have trouble adjusting to their way of doing things. Company culture makes it difficult to establish any decent relationship outside of work. I believe a coworker sabotaged my work prior to a release, which ultimately led to me being let go. I was already planning to leave due to not feeling the culture, but that decision was made for me. Regardless of someone rubbing you the wrong way, doing something like says a lot.
