I applied online. The process took one week.

There was a phone screener and then a coding test within a week. The feedback on the test code noted poor English skills, and there was no positive feedback. They are having difficulties finding talent in Barcelona, and they are happy to pay higher salaries than average.

The code test is to create an "Amortization calculator". There is a need for a rate calculation system allowing prospective borrowers to obtain a quote from our pool of lenders for 36-month loans. This system will take the form of a command-line application.

You will be provided with a file containing a list of all the offers being made by the lenders within the system in CSV format; see the example market.csv file provided alongside this specification. You should strive to provide as low a rate to the borrower as is possible to ensure that the quotes are as competitive as they can be against our competitors'.

You should also provide the borrower with the details of the monthly repayment amount and the total repayment amount. Repayment amounts should be displayed to 2 decimal places, and the rate of the loan should be displayed to one decimal place. Borrowers should be able to request a loan of any £100 increment between £1000 and £15000 inclusive.

If the market does not have sufficient offers from lenders to satisfy the loan, then the system should inform the borrower that it is not possible to provide a quote at that time.
