Pros
Eze does a really good job hiring people. If you're staring in an entry-level or analyst position, you can be almost 100% sure that you'll really like your teammates and you'll have a good time working with them. Most of the managers at the bottom levels are very approachable, hard-working, and they'll go the extra mile to help you. You'll learn some generally applicable skills, but most of what you learn is specific to the industry and the company, and you'll spend a lot of time trying to remember the hundreds of bugs that you have to work around on a daily basis.
Cons
You'll be pressured in to working long hours because of the workload placed on you. This will be sold to you as a "work hard, play hard" culture. Eze isn't the worst place to spend a couple of years, but in that time it will take up a lot of your life, and you won't learn a ton that will benefit you outside of the small world of hedge fund tech. Other reviews have mentioned the reorganization. The company is going through a huge reorganization (really just following the playbook handed down by external consultants) which is mostly done, and it's not surprising that the same senior managers who are underqualified and overvalued are still all in charge of the critical departments. Everyone who has been around more than a couple years can see that the "leadership" of the company just tries to make themselves look good while they pass down half assed "plans" that haven't been thought out, to the lower level people. So, you should also expect to deal with a lot of work that doesn't makes sense or is made harder because someone two levels up decided it looked good on a report and doesn't know enough to realize or doesn't care that they are making a mess.
