Sample Answer

Yes, sir, I have met several clients that constantly complain of muscle fatigue and request optimal diet plans to feel better and get relieved of the issue.

The primary cause of this muscle fatigue is the formation of lactic acid within the human muscles. This happens due to the fermentation of the products of glycolysis, NADH, and Pyruvic acid. In the absence and/or lack of oxygen, these elements get fermented and lead to the formation of lactic acid.

  • Endocrine Glands: These glands lack any duct (pipe) and release all their secretions directly into the bloodstream.

18. Being A Dietitian You Will Be Required To Manage Several Patients By Monitoring Their Diet Plans, Eating Habits and Also Their Preferences. This Will Keep You Busy and You Will Be Required To Perform Several Tasks In A Single Day. How Do You Prioritize?

Dietitians, like every medical professional, are required to closely observe and monitor their patients. This requires them to maintain their daily eating schedules and give them prescriptions besides guiding them about several eating disorders.

Doing several tasks in a single working day requires the dietitians to adopt a perfect prioritization technique so that they are able to perform all their tasks in a time-bound manner. Thus, through this question, an interviewer requests you to share the prioritization technique using which you are able to arrange/ order your tasks.

19. What Are Your Salary Expectations?

It is common for the interviewers to ask about your salary expectations during the interview session itself. This is largely done to ascertain whether or not you and your interviewer are on the same page. Thus, always give a logical reply to this answer by conducting deep research of the industry to which you belong.

Determine the different salaries offered in your profession and calculate an average salary. Your answer must be based on this average salary. However, you can certainly deviate from it on the basis of your academic qualifications and work experience.

20. Prescribing Diets and Preparing Eating Schedules Is A Tricky Job, Wherein There Are Always Chances Of Things Going Wrong. How Do You Handle Workplace Failures?

Success is an ongoing effort, which is a result of your hard work, patience, and perseverance. You just cannot store it or take it for granted, as it is circumstantial. Failure on the other hand is very common and is experienced by people from all walks of life.
