I applied online and after the initial screening they wanted me to do a takehome assessment. This assessment was inherently easy and I completed the requirements. However, as other Glassdoor posts have said, they expect you to implement features that are not described in the assessment.
I implemented extra features described in other posts to amend this but they still found elements I missed. The time it would take to implement a production level set of tests, security, and reliability is really unfair to ask candidates to build in their spare time.
My advice to the interviewing team is to give specific requirements on what features the candidate should include rather than having them guess.
