Pros
Some of the apps the company develops are cool, and genuinely help people with cognitive and language disabilities. If you are a very junior developer looking for your first role, this might be okay for you to stick out 6-12 months to get experience, but please read the cons here carefully.
Cons
I worked overtime most days in what was a very stressful environment. After clocking up 55 hour weeks on a regular basis I was stripped of most of my day-to-day responsibilities in a move that was designed to get me to quit rather than having to formally fire me. In this, if nothing else, the leadership of the company succeeded and I did quit. After that, despite working for the company and being in the office nothing more was said to me, quite literally. No attempt whatsoever was made to convince me to stay, no assistance with finding me another job. Not even a 2 minute face to face sitdown to wish me luck in the future. One of the managing directors did not say goodbye even on the day I left, despite completely parking my social life for months in an attempt to deliver on projects. You might be forgiven for thinking I was just a poor employee, but in the few months after I left, both the head of operations and the most senior developer also left the company. In my new job I'm 100 times happier than I was working here. Please do not be fooled by the nature of the products this company creates that this is a patient or forgiving professional environment. If you have bills to pay, be mindful that job security is not a given here. A perfectly competent employee did not pass their probation in the time I was there simply because leadership decided they did not want her. While in other companies the probation period is used correctly as a backstop in case of a rare mistake or misunderstanding in the hiring process, here it is used more as a free trial of your labour before they decide if you're actually any use. Reader please be aware that by putting this much detail here I have essentially identified exactly who I am to leadership, and therefore removed any chance I might have of getting a reference in the future. I am writing this because I feel I have a duty to don't prevent others from making the same mistake I did, and wasting time in their career when there are so many other better options out there.
