FrontStory interview questions

I had a quick phone interview with the hr , mainly verified that i have high proficiency with big data , python, sql, react and agile. Then i had a 2 hours home task that mainly tested my pandas experience capabilities (+ little sql). I progressed to an interview at the office where i was asked a simple system design question (mainly how to design correctly a backend for front analytics tool]. did not pass this interview but the whole process was very professional.

A team developer gave me a task to build a Wordpress website with specifications for security scalability and such I tried explaining that I have no experience with Wordpress or UNIX yet he said to try anyway felt unprofessional
