I was just going to say something similar to this. The job application is an assessment for your technical abilities/skills for the job.
The interview is a second assessment to gauge your personality and communication to make sure it’s a fit for the team.
There are VERY few jobs where you can work in isolation. Teamwork, personality and communication are important for almost all jobs. Hench the assessment that gauges those aspects.
