My experience with the Capital One recruitment team was long and winding. They have a strange process of making candidates jump through all the standard interview hoops first:

• Recruiter phone screen
• Tech phone screen
• Half-day in-person interview

Only then do they reveal which team you have qualified for. Consequently, going into the process, you have no idea if you will be placed on a front-end, back-end, DevOps, or another type of team.

Then, assuming you make it all the way to the "finish line," you discover that promises made upfront by recruitment are not true.

For example, "Sure, you can work remotely 1-2 days a week" eventually turns into "It won't look very good to senior management if you aren't in the office 5 days a week." I could have saved a lot of time if I had known that upfront.

The actual interviews were fair, but it is obvious that recruiters are not very honest upfront.

Nothing particularly hard, standard CS type questions. Certainly not the 'gotcha' type questions you would get at Google, Netflix, etc.
