It takes 20 days for me to create . Time limit is given 1 month. You have to create filter, pagination, popup modal, add rest api, filter based on duration like past 1 week, 3 month & start date & end date. filter & pagination should update from URL params & many other things. When you submit task after 2 3 days they simply said your code quality is not good so you are not selected. If you go to Big Binary GitHub Repo they will also write the code same as you did. But in your case "code quality is not good" If you reject someone at least came up with some detail explanation when that person spend 1 month to create project. Rejection is not problem but only one word "code quality is not good" make things suspicious. Message for job Seekers :- if you are looking for Task Based Job go to HackerEarth don't waste time in company like Big Binary.
