bullying, hostile managers spoil the entire experience. When I had a problem with a new manager, I found that no one in the entire management chain wanted to let me talk about it. More than one became visibly angry when I tried to tell them anything, or even ask questions. This included Human Resources, whose manager seemed to only want to fight with me and shout me down. Most people will probably never see their worst behavior but at Indeed, HR is not only not your friend--they're your enemy.
Indeed has policies on paper that protect employees against arbitrary treatment, but it's ignored in practice.
Big talk about advancement when I was recruited was a mirage. Indeed is currently hiring rapidly but seems to prefer to hire new people over the heads of existing employees. Salaries are slightly below market.
In-house software: Indeed's operations are dependent on many weird, idiosyncratic home-made software services that are poorly conceived and barely documented. You'll have to learn to deal with these under a management that's far from understanding.
