Is there any hope for me getting a job in what I graduated in?

So I have an MSc one year taught masters in the biotech field, and I graduated in this a very long 6 years ago. I had a gap year between the undergrad and the masters, and I only did the masters because I couldn't get a job after completing the undergrad and didn't have any other plan. Things went downhill during the masters. The third semester (and final) of the MSc was meant to be an industrial based placement. After the interview for the first placement I later refused to give a urine sample to them because I had not yet been offered the position; and this might have been why I did not get offered it. The second position that I succeeded in getting via a phone call interview, I later lost, because when I visited their site I showed up slightly late and apparently seemed "uninterested". So in the end the university had to get one of the professors to come up with some 3 month research thing for me to work on on campus.

The other thing about this masters was that I accidentally missed a 2 day lab training session because it was carried out during the mid-term, and I completely forgot about it. There was no way of substituting for it. So I basically had the whole MSc material covered, but had to return a year later for 2 days in order to complete that module. Therefore I technically didn't graduate until 2019. As a result of this I was put in a dilemma for how to present my CV. I could either mislead anyone reading it into thinking it was a 2 year masters (by putting the dates as 2017-2019), and hope that they wouldn't look up the course... or to list the MSc dates as 2017-2018, and thus risk the date of 2019 being spotted on my scroll when asked for proof. The former way of course may look better, as any idle time since graduation would go unnoticed. As I got a 2:2 in both my undergrad the masters, I thought I'd eb in a good position to get hired, but apparently not.

I didn't get a proper job until 2022 which is in an unrelated field. However I am now on 43k a year, only there's little room for progression in this job and I don't like it very much. So the two main problems with trying for a bioscience job, are that I don't think I'd be willing to take a pay cut, as well as the fact I'm very rusty by now. However, I still get emails from recruiters via linkedin messages, which makes me wonder if there'd be hope. A lot of these surprisingly are for 'senior' lab manager roles, which I wouldn't stand a hope of anyway. I was getting so many email updates from the recruitment websites that I've either blocked or unsubscribed from them. The last person who reached out to me pretty much ghosted me after I told her I'd little lab experience outside college.

I did hate the interview preparation racket. It gets very disheartening when you realise how much knowledge you could actually gain in the amount of time you've spent preparing for interviews. You could nearly go mad when you're memorising answers to hypothetical questions that are very unlikely to be asked. And when you hear yourself repeating the same spiel for the third time in a different interview, you really feel like a fake, and it gets hard to say it with any conviction. The recruitment reps won't lose anything from sending on the wrong candidate to the client… it's the interviewee that will lose, as they are the person that will have to get in their car and travel to the interview. Also, a lot of the job specs read in such a way as if to deliberately give away as little as possible about what the role actually involves. I'm very tired of seeing things like LIMS/Trackwise and Bioburden on job specs, as I haven't covered them in college. Anyway, I would like to hear yer thoughts.

Thanks for reading
