Bit of a pickle re jobs!

honeyD

Ive posted before about my interviews and I was successful with one pending a CRB check, successful induction and 3 month probation. I took this as I will have a job since I know the CRB check will be fine.
Ive now been called for another interview with another company for a job and Im unsure what to do? Ive completed the CRB with the first company and just awaiting that and the induction starts in a couple weeks. My interview is tomorrow! What if I get offered the job.. I dont know what Im supposed to do!
The first job Im not sure how many hours I would get since I dont have my own transport and its a care job and its basic wage until Im qualified.
The second is part time 20 hours basic or just a bit higher wage possibly.
Guess I should see how the interview goes first but Im a worrier! lol.
I hate how this works with the jobcentre and having to keep applying for jobs even when you have an offer!
