It is always more common to receive questions on debt restructuring because there are a lot of consulting firms jumping on turnaround and restructuring services given the macroeconomic situation ahead.

However, your answer is quite weak. 
First debt-service-coverage-ratio (DSCR) is a good KPI but it is useful only in the short term. It may be that 

• the company doesn't have an issue with DSCR but still has too much debt; therefore you have to take into account other metrics (D/E, Net Financial Position / EBITDA)
• over the short term debt repayment is not significant but over the long term it is
• the company generates profits but does not generate cash

The last point is the most important one. 
Cash generation is the most important thing to take into account. Profits can be affected by one-off items and non-cash items, cash can be affected bu one-off items (and you should mention it) but gives you an indication of the sustainability of debt.

As a consequence, there are several other things you have to consider: reduce net working capital and reduce CapEx.

You also have to take into account the future prospects of the company. Is the company able to generate more cash?

My suggestion is to reconsider your answer and craft a compelling and MECE structure that integrates my suggestions.
