Interview
Started with a 30-minute call to get to know each other. Then she asked me to analysis and send it as soon as possible, I asked if they are hiring on rolling basis but she said no we don't and when I asked why you wanted me to send the analysis as soon as possible, she said "The faster you send us the analysis the better the better for you". I spent 30+ hours working on it and made a really good presentation, got an invitation for a 90-minute call with a lead and manager. At this point, I felt like all the comments below were true. I got rejected after this one and the reason for rejection was "My modeling approach is not the best". Please if you're reading this, consider the comments below before applying.
