Pros
A great company with tons of potential to become a leader within the security infosec space. You have your common SV perks: Organic snacks, LaCroix sparkling water, Hint water, Kombucha, daily lunches and weekly in-office Happy Hours. Nothing too special but a way to keep you longer in the office.
Cons
40 hour work weeks are easily 50 - 60 hour work weeks. It's an environment where you can easily burn out. "Unlimited PTO" aren't really unlimited but frowned upon because there's always work that "needs" to get done. The extra hours and time you dedicate is not appreciated but "part of the job". An "excellent" end-of-the year review will earn you a disrespectful raise, don't dare to ask for more because false promises will be made. Promotions are only given to those who are favorited. Majority of the time, it's not even clear what people do to get promoted all the time. Most importantly, Synack is the definition of "office politics". The young executive team tends to isolate themselves from the rest of the company, point fingers at others instead of being accountable, make excuses for goals not being met, pick and choose favorites within the company, and hold many hallways and conference room gossip sessions. This might as well be the next reality TV show. Suggestion/questionnaires during All-Hands is only a gimmick to show that the management team is open to listen but it gets overlooked and brushed under the rug left to be forgotten. A work/life balance is non-existence so if you're looking for a fun cultured environment to work in, this is not the place.
