Hi I will share the details with the shortlisted candidates. Thanks

1- Update application calls should have zero delay so that calls go at full speed. 2- Latency is very important — locally it's 250-300ms, so after deploying on AWS it should be minimum 200ms. So delay = 0 and latency should be low so calls hit fast. 3- We need to pick jobs, and for that we need to eliminate 429, 403, and 504 errors. Why does 429 come? Because we reuse the same token too fast. 403 comes when multiple calls hit from the same IP or combination calls hit together. 504 doesn't come that often, so for that we can keep a retry mechanism. 4- To eliminate 429, we need to use multiple tokens, because a job will only be picked when calls go without even a single 429, with latency 200-250ms and delay 0. 5- For that, we need to do the following: Enter one combination of...

Here is what I expect to see delivered: • Responsive web app where all employees can view and trade shifts, submit availability, and receive confirmation of approved changes • An automated scheduler that produces conflict-free rosters based on roles, availability, and preset rules • Secure role-based access (admin, manager, employee) with an intuitive interface that keeps training time minimal &bul...
