I applied through a recruiter. The process took 4 weeks. I interviewed at Capital One in Dec 2021
Interview
Recruiter reached out to me. We had one intro interview in which I was given the actual application to fill out (Full-Stack Developer). After completing that, I received a take-home technical assessment (CodeSignal / 70min / 4Qs) to do within 2 weeks.
After passing, we scheduled our "Power Day" of interviews. Got a run-down with the recruiter which was nice, but would take it with a grain of salt because some of what was said misled me in my preparation.
Power Day consisted of 2 "Job Fit" Technical interviews, 1 Behavioral, 1 Case. There was a "calibrating interviewer" for the two technical interviews - one was screen-off with no participation, and the other was pretty engaged. The other two just had one interviewer.
1st Job Fit Technical: Systems design
2nd Job Fit Technical: 1 Easy/Med LeetCode problem
Behavioral: 3 Questions, pretty standard
Case: Surprisingly straight-forward, but also not what I expected.
Interviews were fair/easy with proper preparation, but had a negative experience with some of the interviewers who gave some sarcastic remarks.
Interview questions [4]
Question 1
Systems design for a smart electric meter system for an apartment building with one dashboard for tenants to show hourly/weekly/monthly/yearly readings to their specific units, and another dashboard for the owner with similar readings but only by floors or building electricity usage.
Started with big components, and was allowed to delve into specifics in any other area per interviewee comfort and expertise
What do you know about Cloud / why Cloud is beneficial / pros & cons of moving to Cloud.
Given table data, recommend specs for the user.
Interpret code (related to data previously given), then debug
Surprisingly manageable — the interview felt more like a conversation than an interrogation. It began with a sequence of coding questions, including one on merging overlapping intervals. The real challenge came during system design, where I had to outline a URL shortener service that could scale impressively. Interestingly, I had just looked at a similar architecture on PracHub, which helped me articulate my thoughts clearly. The technical questions wrapped up with validating a binary search tree, and I ended with a positive vibe. I received an offer, but ultimately chose to decline it.

Question 1
Merge overlapping intervals from a list of time ranges
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
