Asked me to do HackerRank coding test for 2 hours and 4 coding questions. Although the job description said Matlab is the key coding platform, what was given by HackerRank wasn't based on Matlab (or even R). I am not a cs guy, and sensed that the test was designed largely for cs people. I did coding in Matlab and sent a separate email to the company's HR. Got rejected later. Felt that the company's job description doesn't match with the test.

1 Week after submitting my application, I got an phone screen invitation but later informed to complete a HackerRank challenge before anything. Cleared 2 coding challenges but didn't pass another 2 questions that were unnecessarily hard for non-CS grad. Several days later I asked for an update but replied back with another Math/Logic test (easy) which was timed (30 min). I accepted the challenge and I believe I only had 13/15 correct. It's a mix of GMAT type logic/math questions. But since it's timed you gotta think fast. I admit that the tests were fairly designed and I did not do great, but the HackerRank test was unnecessarily hard for the traditional Financial Engineer role. Recruiter ghosted since then. Overall impression is that this Start-up is heavily in the process of BUILDING the infrastructures then creating models hence the heavy test in coding. Basically everyone should be a programmer. Don't be misled by the job description if you are applying for financial type position. They want programmers.
