I applied online and then received an OA. The system moved quickly (probably auto emails). As soon as I selected a day to take my assessment, I was invited for a job overview zoom webinar while the results were pending.
Interview questions [1]
Question 1
There were a few logic / simple math questions and leetcode easy/medium
The first part was hearing the whole process of what the job would be like, which led into a take-home test, coding/math test. I did not go further than that.
Very long online test required. Some IQ test type questions, some riddles, some learning unclear rules. The grading isn't totally clear (for instance, whether speed of finishing test factors into grade).
