Paragraphs should be compelling in order to persuade the individual reading the letter that you are qualified for the post. Make clear linkages between your qualifications and the job requirements.

Tips for preparation

You will almost certainly be required to write code on paper during the interview. The interviewer is most likely searching for the capacity to think correctly rather than the greatest response. 

Explain why you believe some choices are not realistic. Make sure the interviewer is aware that you are considering optimisations such as space and time complexity, function runtime considerations, and so on.

In DBMS, for example, storage architecture is determined by whether your client has more write operations than read operations or the other way around. Before tackling the issue, clarify these things.
