Pros
AMS has a great client list and when business is going well, there is opportunity to move around. Those that I worked with were smart and hardworking. There is also global exposure, especially on larger accounts with global footprints.
Cons
AMS is owned by Private Equity, and they do a great job of making employees feel valued and cared for, but remember, its always about money at the end of the day. Do not lose sight of this as an employee. Their "Assignment Based Culture" is a stand in for volatility and the idea that "when one industry is down, another is up," is not an accurate representation of how economics works. When business is not doing well, they lay people off. Not everyone gets reassigned. The bonus scheme is pretty brutal, as well. 6 month waiting period to begin accruing, and then if you are not at the company when they pay out (The bonus policy is misleading at best - it says that they can make exceptions if you are laid off, however, they will not. This caveat is just in there to misdirect. Be aware of this - like I said, it's about money and if they will save a little money by doing layoffs before bonuses are paid, they will.), they will not pay your bonus, even if you worked the full year. I think recruiting (positions) will be negatively impacted by AI in the coming years, so if you are not a senior level employee responsible for relationships, you may be at risk. I note below that that I have a positive outlook on the business. This is because I do expect more hiring over the next 6 months but I also anticipate that AMS will look at AI investments, which I believe will also help their business, but I do think that it will be a great thing for the actual recruiters that are employed by AMS over the long term.
