My process consisted of a code signal exam with 4 medium to hard questions, power day with 4 rounds of interviews, and then met with Director. Process and offer happened quickly.
Interview questions [1]
Question 1
How would you handle UI testing for multiple languages?
I applied through a recruiter. I interviewed at Capital One (New York, NY) in Apr 2023
Interview
It was pretty simple. You start of with a assessment through code signal. It's 70 mins and protocored. The questions start off easy and then progress to med/hard level. You can pick any language. The recruiters are typically helpful, they give you a lot of interview prep for the "power day" which is 4 interviews. You have a standard DSA problem thats typically medium level. Practice leetcode but its doable. Then its a design problem where you create a backend system of a credit card application. I guess the design problem might vary if you are applying for a front end of data engineer role. Then there is a behavioral round with 3 questions. And finally there is a case study. It starts off with some conceptual questions. I had one around some chat bot usage. Then you analyze some code and based on a table of data give an output. And finally you get to make some code improvements and recommendations. I declined the offer because I applied for a role in one location then magically it closed like 2 weeks after. it was in New York and they wanted me to relocate to McLean. The recruiter mentioned a range of salary for New York which was like 20k higher than what they wanted to offer me for McLean. No thank you.
Interview questions [1]
Question 1
1. Codesignal - dont remember the problems but I assume its from some question bank. Practice leetcode easy/medium problems around arrays, string manipulation, collections, and using pointer/sliding window approach.
Power Day Rounds (4 interviews, 1 hour each)
1. Coding - Given a string, find the total count of some character. They expect a O(1) solution as the optimal solution.
2. Design - create a backend design for a bank application. Watch youtube videos by Exponent, this is really helpful. You should list out requirements, pick out all the components to address each point, some sample database table schemas, and some sample REST API's. Theres follow up questions based on your design but overall each on of these videos has similar components, its just how you explain things. You should also recommend technology for each component you'd use to make your decision stronger.
3. Behavioral - forgot the questions but its usually things like: tell me about a time you had to learn something new, tell me about a time when you have multiple priorities, etc. Typical STAR format interview questions they can be found everywhere on google.
4. Case Study - I had one around some chatbot. They ask conceptual questions like what are the pros/cons of a chatbot at a bank, how can it help customers, know things like data & privacy concerns with chatbots. Then code analysis is simple, just know basics of Java and understand OOPS.
I applied online. I interviewed at Capital One in Oct 2022
Interview
I recently went through the interview process at Capital One and wanted to share my experience to help future candidates be aware of potential issues. Initial Interview and Code Signal Assignment (10/25/22) - My first interview with Capital One took place on October 25th, 2022. After passing the initial conversation, I was given a code signal assignment which I completed successfully. Ethics Review (2 months) - As I have a side gig as a freelancer, the company put me through an ethics review that lasted around two months. This was a long and drawn-out process, but I appreciated the company's attention to ethical considerations. Power Day Interview (12/16/22) - After the ethics review, I had my power day interview on December 16th, 2022. Role Reassessment - Soon after, I received a call from my recruiter. They informed me that, while I performed well in the interview, they believed I was not at the level they initially interviewed me for (Manager). Instead, they offered me a lower-level position as a Principal Associate, which I accepted. Hiring Manager Interview (01/13/23) - My recruiter passed my resume to other hiring managers, and I had an interview with one on January 13th, 2023. The interview went well, and the position seemed like a good match. Restructuring and Delays - Unfortunately, on January 19th, 2023, I received an email from my recruiter explaining that the team I interviewed with had gone through a restructuring and they would not be moving forward with my application. Ongoing Communication - Since then, my recruiter has been circulating my resume to other hiring managers to find me a team. I have been checking in once a month for updates, and they continue to assure me that they are actively looking for a team for me. However, no progress has been made. Overall, the interview process at Capital One has been lengthy, frustrating, and disappointing. Despite performing well in the interviews and being offered a position, the company has been unable to find a suitable team for me. The lack of progress and ongoing delays have negatively impacted my experience with Capital One.
Power day interview part two: Pair code assignment with two developers. It was a code signal easy problem with a focus on giving the solution as production ready as possible.
Power day interview part four: Behavioral Questions: they will ask you around five behavioral questions from a list they provide in their preparation material.
