Tier 2 visa delay

I would like someone to guide me with my current situation, I have switched my tier 2 visa to a different employer after 2 years, application submitted in Dec 2022, they couldn't process it on time, I got a letter asking for interview which was held in June 2023 and am still waiting for the response . The question asked in the interview were very basic about my job role and place I will be working nothing serious.

Can anyone help me I have been waiting since June and there is no response from home office .
