Pluspunten
All advantages have been wasted away. Couple years back this outfit could have seriously challenged Amazon and the likes but likely it will not survive couple more years. Only pros as some have mentioned earlier are decent salaries while you really look for your next job away from madness and get your H1B done through them.Also if you are out of station candidate, use them to get your relocation done etc.
Minpunten
Just too many to list so will only mention themes- incompetent senior leadership (virtually bulk of VP+ folks), incompetent CEO who has no domain knowledge of the business, constant and maddening re-orgs to hide lack of work delivery, intense politics to get rid of people who can threaten survival of few top leaders who are mostly incompetent and ignorant, ludicrous leveling like few VPs who actually are senior manager level. If you are smart and can work for other top notch firms in the bay area like google, facebook, apple etc. then stay away unless you want to use them for relocation, H1B etc. as mentioned above. Every few months there are mass exits of people leaving voluntarily while the CEO and CTO spin stories to hide their incompetence and lack of knowledge. Excessive influence of Bentonville and they even inject their own clueless people in ecommerce arm. Most of them fail and waste more time while the world around Walmart.com is everyday innovating. I have a sell rating on this company. It likely will not even come close to giving Amazon any real competition.
