I applied through other source. The process took 2 months. I interviewed at Koalafi
Interview
4 interviews and one onsite interview. At the end of the last interview, an Exec told me that it would not matter what skills I had since I do not have a Math heavy Graduate Degree or Phd. I felt like asking him on the spot.. why did you waste my time?
Thank you very much for taking your time to interview with us. We regret you had a negative experience as that is definitely not what we want our candidates to experience. We invest a lot of time from our staff getting to know each of our candidates and apologize you felt like your time was wasted. Thank you for considering West Creek.

I applied through a recruiter. I interviewed at Koalafi (Washington, DC) in Nov 2025
Interview
I spoke with the recruiter, then hiring manager. I didn't make it past that point (unsure why).
The recruiter and hiring manager seemed nice, but the recruiter didn't respond to my follow-up email asking for feedback about the interview process. That left a bad taste in my mouth.

I applied through a recruiter. I interviewed at Koalafi (Centreville, VA) in Apr 2021
Interview
First time I've ever intentionally botched an interview. Interviewer was very arrogant and belittling. Wouldn't even allow me to answer a single question before interrupting. I'd be happy to get rejected if it means never interacting with this guy again.
The process took 2+ months. I interviewed at Koalafi (New York, NY)
Interview
Stay away from this company. The interview process is highly unorganized and they don't test data science knowledge, but your ability to solve maths questions! They are trying to imitate the data science process at Capital One and the job is actually a Business Analyst role. The company has high Revenue growth, but profits? Is it going to survive during a market crash?

Question 1
Just mug up all the capital one cases ( no ML knowledge is required)
