I applied online. I interviewed at Red Hat in Nov 2021
Interview
You could apply for 3 internships at once (they had numerous internship positions open). Firstly, you received a call from an HR employee. Then you were invited to a real interview, which was conducted online with 2 employees (one of them was the manager of the team). After that you waited 2 weeks for the results. If you weren't selected, you can apply for another intersnips (that remained free) or only ask for the reason that they chose another candidate.
Interview questions [1]
Question 1
They asked basic questions about your experience in the field, your education, your interests. They were curious why you think you are the one for the job, how much time do you have, etc.
