Applied online for Backend Engineer at CloudFlare and got invited to the online Hackerrank challenge.

Got two questions

1. Use a Rest Api to list out Spiderman movies released in sorted order
2. Validate IP Address

Upon completion i got a email from the hiring manager to schedule a phone interview.

Phone Interview:
He started out with the basic introduction of the company and his role and team. Was really professional although i could not understand his accent much . Started off by asking what i did in my previous job and any projects i was proud of.He then moved onto tech questions.

Technical Questions

1. Can you describe what happens when you hit a url in the brower? (Http request/response etc...)
2. What will you do to ensure correctness if your DB has a lot of incoming traffic.
3. How to check the correctness of Microservices when all of them are being developed independently.

I answered all of them and he wrapped up the call. Got my rejection mail four days later.
