Pros
If you work at ReliaQuest, you are pretty much guaranteed to grow exponentially from a personal and professional perspective. The experience you pick up is some of the most highly valued in the IT Security realm. This is an organization built by the smartest and most talented individuals under the direction of top-tier leaders.
Cons
This isn't the right place for everyone. If you are ambitious, talented, and willing to stand out amongst a group of other, very smart people, you will do fine, however, if you are simply looking for a 9 to 5 paycheck, you may need to take a step back and think. I can tell you that there is always work to be done, and never a dull moment. I can probably count with both hands the number of "slow" days I've worked, but it certainly pays off.
