Consider your availability for interview, ideally hold a few days of holiday back and earmark these as time off to attend interviews.
Start keeping a diary of what you applied for, when and via whom if you have been represented. This way you will be well organised and also you will know what to follow up on and when. This especially applies if you are in a market where you can make multiple applications for similar roles i.e. if you are going for a Lab Technician role in the Pharmaceutical market.
