I think I looked for work for about 5-6 months before finding my current job.
I applied for literally hundreds of jobs and was starting to get really despondent that I wasn't getting anywhere. Before having DD, I worked in PA/senior administrator jobs in universities and educational institutions. These were the jobs that I initially applied for, but as I was getting nowhere, I started applying for more junior roles, then for entry level roles. It was getting very disheartening.
At that time, the place that I now work for was advertising several positions. I applied for a part-time reception/admin job, but then got a call telling me that they thought I would be more suited to the full time management position and asked me if I wanted to apply for it, which I did. I made it clear from the start that while I was happy to work full time, I was still breastfeeding DD and asked how I could manage this. I've been there for over three years now.
