QC chemist | Pharma interview Questions & Answers | Pharma Udyog | Interview

1. Question 1. What Does A Quality Control Chemist Do?
   Answer :
   Quality control: testing samples of raw materials or products either in mid-stage or close to final stage to make sure that they are of high enough quality, teaching the standards and qualifications, before the product can be mass produced.
   • Research and development of products.
   • Perform various chemical methods and procedures in the lab.
2. Question 2. Specifically, What Company Do You Work For, What Is Your Official Title/position, And What Are Your Duties?
   Answer :
   Example:
   Lead chemist: works in the lab, chemical reactions, testing the products, analyzing, quality control of raw materials to match all the qualifications/standards, quality control of final product, whereas the chemical engineer does the processing and development of the product.
   Company: Javo-Mex (soap/detergent/body wash/hand soap/cleaning products company; manufacture for P&G, Mr. Clean)
3. Question 3. Could You Describe Your Typical Day At Work?
   Answer :
• Take samples of raw materials or the finished products to the lab for analysis.
• Follow different chemical methods to do analysis to make sure samples have reached qualifications.
• If not reached qualifications, must tell the supervisors and stop production to find the problem.
• Inspect other co-workers.
• Fill out a sample report (raw materials, final products have different reports).
• If the raw material/final product/mid-stage product is poor: give the report to another department.
• Once final product is approved, send to packaging department and then they will ship it out.
• Once raw materials are approved, send to processing/manufacturing department to make the product.
4. Question 4. What Is Your Work Environment Like?
   Answer :
   • In a company laboratory.
   • Must always be sanitary.
   • Sometimes if there were a problem, had to go to manufacturing department.
   • Go to warehouse to sample the raw material.
   • Get finished products from the production/manufacture line.
5. Question 5. Who Do You Work With Directly?
   Answer :
   • Director of the quality control department.
   • Chemists, chemical engineers, mechanical engineers, electrical engineers (if manufacturing has problems, they may consult me, or chemist consults them).
6. Question 6. What Are Some Of The Challenges You Face At Work And How Do You Overcome Them?
   Answer :
   Understanding all the chemistry, following the manufacturing/production rules and standards.
   When something is wrong with the raw materials:
   If sample is not good, call the raw material manufacturing company, and send back the materials.
   When something is wrong with the final products:
• If sample is not good, keep hold of product and find out the problem by contacting the different departments.
• Solving the problem is hard; meeting with different departments to solve the problem.
• Tracing back to the processing stages of product.
7. Question 7. Around How Many Hours Do You Work Per Day, And How Many Days Per Week?
   Answer :
   • During the "high season" (summertime; higher demand) : overtime --> 10 hours or more
   • Regular season: 8 hrs
   • During "slow season”: 8 hrs
9. Question 8. What Is Your Favourite Part About Being A Chemical Engineer?
   Answer :
   • The chemistry knowledge you get to apply
   • The technology
10. Question 9. What Is Your Least Favourite Part About Being A Chemical Engineer?
    Answer :
• Exposure to toxic/poisonous materials (not healthy for the workers).
• Boring routine, doing same thing over and over, monotonous.
11. Question 10. What Are Your Skills And Attributes That Make You Fit For This Job?
    Answer :
    • Knowledge of chemistry
    • Chemistry or chemical engineering degree
    • Communication
    • Attention to detail
12. Question 11. Can You Go Over The Qc Chemist-specific Technology You Use?
    Answer :
    Different types of instruments: HPLC (high performance liquid chromatography), Infrared spectrum, viscometer (specifically rotational), colorimeter, pH meter.
    Use computer analysis with HPLC.
13. Question 12. What Are Some Of The "chemicals And Substances" That You Utilize And What Are They Used For?
    Answer :
    sodium hydroxide --> adjust pH, hydrochloric acid --> adjust pH, sodium chloride --> adjust the viscosity (for hand soap), different kinds of pigments to adjust fragrance and colour, various strong acids and bases, propylene glycol and sodium xylene sulfonate to adjust viscosity, indicators.

17. Question 13. Could You Give Me An Example Of The Methods You Use In Quality Control?
    Answer :
    • For detergent: check the colour, smell the odour.
    • Check the pH is in the range using pH meter: specific ranges for specific products.
    • Specific gravity is in the range.
    • Check the viscosity with viscometer.
    • Wet chemical method/titration used to check percentage of efficient chemical and concentrations.
    • Micro confirmation test: Make sure no bacteria in the product.
18. Question 14. Can Inform Me About Your Educational Background And Credentials, Such As What Undergraduate Degree You Graduated With, Master's Degree, Professional Degrees, Etc.?
    Answer :
    • Master’s degree in chemistry (specifically in polymer) at University of Detroit.
    • Undergrad degree in organic chemistry in China.
19. Question 15. Which Chemistry Courses Did You Find The Most Important For Your Career?
    Answer :
    • Organic/inorganic chemistry
    • Analytical chemistry
    • Physical chemistry
