Although it may seem strange to some people, there are many reasons why a job seeker would want to work as a temporary employee. Job seekers from the beginning of their career into retirement age can all enjoy the perks of temp work. Some of these benefits include:

Flexibility - As a temp worker, you can agree to take or turn down work at your leisure. For retired individuals who travel a lot, temp work is excellent for seasonal needs.
Buying time - Temp workers can earn money as contractors until they find the right permanent opportunity.
Compliance with work restrictions - Temp opportunities are often a better fit for people waiting on permanent residency or citizenship who may have federal work restrictions.
Fill resume gaps - Temp work offers job seekers the opportunity to learn new skills in various settings, thereby expanding their resume.
Fast-track to employers - Temp employees are often offered a permanent position after their assignment is complete if the hiring authorities are impressed with their performance.

Discuss with the interviewer why you believe some candidates would prefer to take on temporary assignments.
