PepsiCo Chemical Engineering Placement interview questions

Firstly it was a standard application process with questions, experience etc. After a few weeks they got back to say I had a self recorded video interview style assessment. This was fine and a few weeks later I was contacted to say I'd gotten to the assessment centre day. This was made up of a very standard interview (retail job level to be honest), a group activity and a tour of the office. However, almost two months later they have never gotten back to me. This is after multiple attempts to contact them. This is a very dissatisfying outcome from a company like PepsiCo.
