Interview started with basic intro and past company projects after straight moved to the MongoDB queries like push pull into array of key in a document and $ne to exclude something it was basic queries Then socket io how it works and basic chat design system after that moved to js program of printing n 1 to 10 with an interval of one sec then there was a react component to create in which you have to create it with button to start printing number with 1 sec difference from 1 to keep moving on clicking again revert the to zero again. My take I didn’t get any feedback what went wrong i think rejection was of some queries was wrong that’s why they rejected Overall interview was good but it would have been better if they had given a feedback to work on.
