Visa Inc. Software Developer interview questions

Great interview process with 3 rounds. Two technical and 2 behavioral, asking questions about past projects and experiences. Everyone was kind and I ended up accepting the offer. Great company culture so far.

The first step was an online coding assessment from Codesignal. The coding questions were not difficult, but the last question needs the optimal solution to get full marks. Did not get an interview for the next step with 3/4 questions fully correct and a majority of the test cases in the last question correct.
