Transcribing the interview
If you have recorded your interview you will need to transcribe your recording onto paper. This can be a very time consuming process. As a guide it would take an experienced audio typist 6 hours to transcribe 1 hour of interview recording! It is good practice to number each line of your transcript for easy reference later.
Whilst transcribing your interviews, you may want to add any notes that you made during the interview to the transcript itself. You may also want to add any codes if you are coding your results.
Coding the interview
If you intend to interpret the data you have gathered in terms of themes, concepts or ideas then you may find it useful to code your transcript as you transcribe it. Coding involves assigning a particular theme or idea a number (the code) and then marking the code next to any text on the transcript that concerns the relevant theme. Of course you could use a key word rather than a number if you prefer,as long as all of your interviews are coded in the same way. You will then be able to easily identify any particular theme across all of your interview transcripts. If you are using a structured interview then your codes can be pre-set for every possible answer that the interviewee may make.

If you have made notes whilst recording your interview then leave a column next to your transcript so that you can add them in as you are transcribing or have sufficient room to add them once your transcription is complete. You should place your notes next to the relevant part of the transcript text. You should not confine your notes to things that were written down during the interview. You can use the transcription process as an opportunity to re-evaluate your interview and record any further notes that come to mind.

Some software packages are available that allow you to transcribe and make annotation against the interview recording. Check with your supervisor to see if any software is available within your department.
