This was for a 12 month contract role.
After submitting application, it was a month before they responded, then set up an interview.
Interview was with a panel of 3 from Ineos asking competency based questions from a specific list.
Most disappointing was trying to get feedback after the interview. Having asked every week for the outcome, I eventually gave up asking as "waiting for all scores to be gathered" after 2 months is not very helpful for a 12 month role.
I'd suggest that quicker decision may make the business more effective.
