Pros
Military like operation. As an asset, your value is based strictly on your impact to the bottom line, work late and weekends and you may get a promotion, but its doubtful, because they reworked the way performance reviews are done so you need to directly work with customers, which is tough for most engineers.
Cons
Under Aron Ain the company was amazing, he was an amazing leader/CEO. Aron instilled a sense of community and compassion. When Aron left Chris Todd took the helm and with him Hugo Sarrazin began to make changes based strictly on revenue and profit. If you like the way Elon Musk runs Twitter, this is your company. HR reaches out to recently promoted people and asks them to leave a favorable review on Glassdoor, that should tell you everything you need to make a decision about this company.
