Zelus Analytics interview questions

Basically the same in this startup for all the roles. An async written Slack interview replaced the typical phone screen in order to learn the written capacity. Then came a short session with the contractor recruiter to discuss the logistics. Later 2 technical calls came simultaneously: one was in a group which suggested you to present something in a slide in front of the director, lead product manager and a senior; later, a code review on the take-home assignment (it was assigned right after the call with the recruiter). The third was said to include 2-3 talks with some members from the management though I got only one more technical talk with the senior that I met in the previous round. I got the request to do referral check soon the second business day after the 1-on-1 call. But it didn't guarantee an official offer.

It starts with a written Slack interview (which took me a day to write excellently), then a take-home assignment that took me 3-4 days, including analytics+ML model+design+productionizing. Then an interview that includes questions on take-home and some ML based questions. Then comes a presentation round where you present a project which took me a day to prepare. Honestly, it took me a total of more than 6-7 days fulltime to prepare for the process - only to be rejected with a generic email. Everyone i met were nice but very poor communication. One of the worst after-decision experiences.
