Avantages
Higher PTO than industry average. Benefits solidly "average", but types of benefits are comprehensive. A number of corporate partner discounts available for employees. Fairly extensive online training resources for employees for things like certifications.
Inconvénients
If you're a temp-to-hire employee you get nothing from the listed Pros at all until you're hired. Chances of being hired out of temp-to-hire fairly low. Base pay is low-to-average; non-advancement raises or annual bonuses after you're hired are nonexistent(a new reason is cited every year, guess-the-reason is something of an internal office game). Depending on the contract you are hired into, training in specific client systems may be scant. Company is deathly afraid of overtime pay, so if you're hourly you're highly unlikely to get overtime, however if you're salaried you better believe they know they don't have to pay you overtime.
