The ease with which you can upload multiple CVs is fantastic! Also they send reminders if I haven't submitted my CV in time for an interview that are very useful - not so much when it comes back marked as "unsubmitted". It's great having everything uploaded into one place but sometimes there will be something missing or out dated from another application process (such has been updated since). If looking at different companies then uploading each document separately could get quite tedious over many applications though this isn’t always possible either due too other documents being required by employers such us cover letter/resume etc.
