Pros: People, the team itself seems to be very glued in and exciting.

Cons: I went through the full interview process for a role in Amsterdam. The process itself was thorough, and the people I spoke with were knowledgeable. Compensation was competitive, and they were transparent about the 30% ruling benefits. After receiving and signing a contract, I resigned from my previous role and began preparing for relocation to the Netherlands. IMC rescinded the offer. I don't know how going onsite for interviews and taking a holiday day off to ensure I could be present does not signal commitment to joining the company. There was no warning, no opportunity to address whatever concern they had, just a withdrawal of a signed contract before I was due to start. This left me unemployed with no notice. The inflexibility from themselves is a worrying trend. On that basis, I would encourage potential candidates to continue with other opportunities to avoid the outcome I experienced.

Pros: Few people are genuinely good. Very good hardware and execution performance.

Cons: Basic pricing and strategies. Privately owned, with no option to invest your own money or give equity to employees, so you'll never feel it's your company. Managers used to be the best engineers/traders, and this doesn't necessarily mean they are a good leader or manager. High pressure and demand to deliver a lot with high quality in a short time, and then fingers are pointed when bugs are discovered. It feels like working for an immature company, and at the same time, it doesn't offer benefits similar to startups (equity/stocks, true autonomy, and full ownership). Your review cycle and bonus can easily be influenced by politics and favoritism.

Pros: There is a decent work-life balance for HFT.

Cons: The bonus range can vary widely.
