Perguntas de entrevista de vagas de Robotics Engineer Intern da empresa Techolution

I applied for the job posting, contacted the recruiter, and arranged an intro call with an engineer to discuss my background and responsibilities. Then they ghosted me. After a few months, I was again contacted by the same recruiter, but this time instead of arranging the intro call, they asked me to write a detailed report on designing and prototyping a robotics end effector. I spent like a day finishing the report after which they ghosted me again.
