Accepted one job but now have another job interview !

[2coldinscotland]

Hi, I have been a SAHM for 8 years. Now is the time to return to employment. Accepted job offer which is fine but not ideal . Have just received another invitation to interview . The recruitment process has taken 4 weeks so far. aibu to go for interview ? What if I'm offered this second job? What is the etiquette? Original company would then have to interview again & wait a further 6 weeks (this is how long process has taken)

Go to the 2nd interview. Might not get the job anyway. See what they offer. They may offer better salary/working conditions.
I was in a similar situation last year. The 2nd job offered worse pay but way better conditions, I asked if they'd match the salary job 1 offered. They did and I still work there now.

You wait and if you get offered another job, you make the decision then.
