I applied through college or university. The process took 1 day. I interviewed at Capital One (McLean, VA) in Feb 2016
Interview
I met some recruiters at my school and they told me to apply online for the Technology Development Program. I received an email about a week later asking to pick a date to come interview at one of their offices. The interview had three parts; technical, case, and behavioral.
The technical interview was pretty standard, just some questions about strings, linked lists and how you would design a system in an object oriented fashion (What objects, properties, data structures).
The case interview involved hearing a real-world business problem and deciding which options made the most sense for the company. This involved setting up some basic algebraic formulas and determining which one makes the most finical sense. They don't expect you to know be perfect at this, but they want to see you talk through your thought process. If you get stuck, they will kind of nudge you in the right direction.
The behavioral interview was pretty straight forward. They asked you to describe situations where you had to work with a team and what worked and what didn't.
Overall a very positive experience. Everyone is really nice and the interview felt way more relaxed and less stressful than other interviews I've had.
Interview questions [1]
Question 1
Determine if a string is valid based on placement of parenthesis. i.e. "123(13(44))" is valid but ")234(12)(" is not.
Interviewed for an engineer position, the interview was a joke. Asked basic OOP question with a few follow ups - no system design portion. Interviewer was very laid back and chill, didn't take it to seriously.
Was not too difficult. three total interviews all on the same day back to back. technical one, behavioral one and a case which was more of just a debugging question
Expecting a challenging experience, I found the interview at Capital One to be intense, particularly during the system design section. The question on designing a rate limiter with a token bucket algorithm took me by surprise; mid-way through the problem, I realized it was very similar to a drill I’d practiced on prachub.com just days earlier. The technical rounds included several DSA questions, and the interviewers were thorough but supportive. Ultimately, I received an offer and happily accepted, feeling well-prepared despite the pressure.

Question 1
Design a rate limiter using a token bucket algorithm and discuss how it would handle bursty traffic and distributed deployments.
