Stobbs IP interview questions

Shocking overall experience. For the daughter company of Stobbs, Obviously. Initial round screening call with an engineer make sure I am who I say I am. Given a test post first round to do at home for review. Passed that and got to a final round panel interview 45 mins in the office. Received offer, to then have the offer retracted due to "internal miscommunication". Been told I need to redo the take home test. Week later told the role wasn't offered to me. AVOID at all costs horrible communication and waste of time. Interviewers were friendly but I believe that to be the face of it.
