Solicité el puesto a través de un captador. El proceso duró 3 semanas. Acudí a una entrevista en Capital One en jun 2021
Entrevista
Process (~3 weeks):
1) Cold contacted from recruiter
2) HackerRank: Online assessment
3) Power Day: 4 hours of back-to-back 1 hr block virtual interviews. 1 - Coding, 1 - System Design, 1 - Behavioral, 1 - Business Case Study/Coding
Experience:
- Very disjointed, unorganized scheduling.
-- Example: Not given the proper links to interview until minutes beforehand. Had to re-do a block weeks later due to another initial scheduling error.
- Interviewers all nice but questions/expectations were vague and answering process mismanaged.
-- Example 1: Interviewer asked systems design question but did know how to use HackerRank tool for assessing answer. Expected candidate to know how to use "white-boarding" tool seen for the first time, and produce design diagrams in 45 min, but did not specify any details on their expectations, besides overall vague "design" question.
-- Example 2: Interviewer did not know how to access HackerRank for a coding pair and expected candidate to solve technical access problems. This significantly cut into coding time. When finally accessed, question was presented unclearly, and interviewer rushed through problem solving process, due to access issues earlier.
- Overall professionalism was lacking.
-- Example 3: After meeting with 7 different people for 6 hours overall, received automated "application" rejection. No feedback, no follow-up. Not even provided with emails to thank interviewers for their time. Obviously, to be expected for big companies in 2021, but still not professional.
4 rounds of interview including coding , design , case study, behavioral after clearing the code signal assesment. Coding was medium hard of 2 questions each. case study and system design was difficult.
This took a bit longer than expected, stretching over several weeks. The technical rounds were intense, featuring an LRU cache implementation and a problem on detecting duplicate transactions within a 60-second window. I was nervous at first, but it clicked for me when I realized I had practiced a similar approach on PracHub just days before. Unfortunately, I didn’t receive an offer in the end, but the experience was a solid learning opportunity. The behavioral questions felt straightforward, so I wish I had made a stronger impression in the technical segments.
