Istra interview questions

writing exam with classical quant questions: The questions on the writing exam were particularly demanding, with a level of difficulty that was reminiscent of math olympiad-style problems. Despite the challenge, I found the questions to be engaging and stimulating, as they required me to think creatively and apply my knowledge in new and innovative ways.

Regular phone call screening. Nice interviewer, gave feedback during call. Asked questions in probability and in algorithms & complexity. Phone call lasted about 45 minutes. I didn't do my homework, and wasn't prepared for the interview. A revision of probability brain teasers and puzzles is recommended (dice, coins, basic sorting algorithms ets).
