Pros
Like the government: steady, safe, reliable employment. Free Lunch Weekends are truly off--and Fridays are quiet due to Israel being out. you do always pay for it by feeling behind on Monday. I think the Israelis think we don't actually work 5 whole days. you can get paid fairly--but you must negotiate heavily for it. I had to walk away from the job offer 3 times before getting what I wanted. I had an incredible manager there, but that person is now gone. If you are shielded from all the difficulties with Israel it can be a safe steady mostly 9-5 job.
Cons
This is not a marketing driven company by any stretch. Every quarter you will spend half your time justifying your entire existence to Gil personally, who won't bother to actually hear your entire power point presentation through before cutting you off at the middle of slide 1 to harangue you about his theories of marketing. Since you can't spend more than $25k on ANY ONE PO, you are essentially justifying every spend you make to every single banner ad purchase. It's also tremendously convoluted, the purchasing organization is set up like the Soviet government, with instructions to obfuscate and reject purchase orders because they don't like the way the justification is worded. I have an MBA from a top program and more than a decade of experience in my field, and justifying my marketing strategy to a low level clerk (who would then explain it to Gil's cousin, who would then explain it to him and screw it up in the process causing it to be rejected), just grew too exhausting to put up with.
