Audi UK interview questions

Process was easy but not fair. I have been invited for interview and it was case study based presentation. very next day got call from HR saying their was nothing wrong with me but someone internally applied and hence position was given to that person as per company policy. I would say whenever a organisation go for external hire, they first check internal recruitment and then call for outside candidates. This made expectations from me but finally ended up at loosing side even when my interview went well with feedback to apply again in future.
