It’s part numbers game and part of the ‘face fits’. The labour market is cooling a little and they recruiters / hirers have so many competing demands on who and if to hire. Keep at it and try and keep that positive (it’s all a learning experience) outlook

It seems to me, and I am happy to be corrected, that some interview coaching would be a good idea. Being good (and trainable/coachable) at a job rarely come across well at generic interviews. 
You can do it for free via YouTube.

Look at Saylor Academy for some course to round out your skills / communication. It shows you are open to learning and recognise there are skills you want to work on - and are prepared to - in your own time.

I work minimum wage in manual labour - it is destroying my body and my mind - please take it as a cautionary tale. Semi-skilled is preferable .
