Pros: Competitive compensation Relaxed working hours Friendly colleagues

Cons: Communication can be improved Security is a bit of a theatre

Pros: Frankly a great company to work for. The people are extremely smart, dedicated, and nice. Work is impactful especially when working with quants. Hours aren't particularly long and environment is laid back. Very diverse problems to solve and things to build, from high performance financial algorithms to web services. Great perks (free lunch, lots of holiday (30+ days), actual free cafe in office with professional barristas)

Cons: The culture of secrecy is still very much a thing, albeit not as bad as in previous years (or so I've heard). I have to leave all electronics in lockers when arriving at the office. Half of the company (quants, engineers, etc) is forced to work in the office full time with 3 days of WFH (but gets extra holiday), other half can WFH as much as they want but can also opt into working in the office full time to get the extra holiday. I'm happy to work in the office, but this is a con for people with families. It is very much white male dominated, especially in engineering. GR badly needs more diversity.

Pros: Positive working atmosphere - people help each other out, no prima donnas Smart colleagues - the standard overall is by some way the best I've ever had in a workplace. It's a great place to learn Sensible work/life balance - the emphasis is on sustainable work, no-one is expecting any death marches I find the day-to-day work interesting and challenging - we are trying to get and stay ahead of others in our sector, so things don't stay still for long It is a great location. It's growing, so there are opportunities for those who might want to end up managing others Solid business model - I think the company is very well placed for the short/medium term (which is as far ahead as I care to predict) It has decent pay. Reasonable selection of soft drinks, although I am still not sure whether Diet Lilt should have made the cut

Cons: Security concerns mean home working is off the menu. Not a problem for many, but a major drawback for me It's growing, so it's not as small as it was - not a problem for me, but some might prefer a sub-100-employee type setup
