The time of repayments depends on the loan type. The payments for the long-term and leasing loans happen monthly according to the schedule: you get part of the principal amount + part of the earned interest. The payments for business and real estate loans also happen monthly, but you get only a calculated part of the interest, the principal amount is paid after the loan is closed. The payments for the short-term loans happen after the loans are closed, you will receive the full principal amount with earned interest.
