A sample answer to question 1

What does a typical day as a mortgage administrator involve, and what do you think makes someone good at it?

A typical day starts by checking the case management system for new applications and any cases that have hit a deadline. I would log new submissions, check they are complete against the lender's checklist, and request anything missing from the broker or customer, such as payslips, bank statements or proof of ID. Through the day I would chase valuations, keep solicitors updated, answer broker calls and emails, and record every action on the file so anyone could pick it up. I would also be watching service level agreements, because a case that sits untouched can delay a customer's completion date and a house purchase chain. The best administrators are accurate, organised and calm under volume. They are persistent without being pushy, they communicate clearly and they take ownership of a case until it completes. I also think curiosity matters, because understanding why each document is needed makes you quicker at spotting problems.

Common mistake to avoid: Describing it as just data entry; ignoring customer and broker contact
