The interview process consists of one preliminary coding test and an onsite if you do well on the coding test.

An onsite consists of five rounds, including one where you formally meet their corporate recruiter and discuss HR/logistics questions.

The format and the questions asked are consistent with what other interviewers at DraftKings, who have posted on Glassdoor, have stated.

It's a pretty standard and straightforward process.

Make sure your OOP skills are above average. Don't only implement the classes/models for the OOP design but also implement the controller and the entry point for the app. You will do fine.

Also, make sure to have superior parsing skills with JavaScript on the first round.

First is a coding round (validate a lineup).

Basically, parse and match stuff across multiple JSON documents. Implement logic to validate a lineup before a game. You can only use Javascript.

OOP question: Design a restaurant where there's a robot that takes orders from incoming customers, delivers orders to the chef. Robots also bring back the food and are tasked with keeping a tab and generating the check.
