Ensure questions are open-ended to elicit detailed responses that reveal the candidate's thought process and approach to work. Step 6. Conduct initial phone screening.

Sifting Process in Pharmaceutical Manufacturing:

Sifting is a screening process to exclude foreign matter / particles (if any) and particles beyond the required size. Sifting is carried out by allowing particles to pass through specified mesh under the influence of vibration and gyration. The mesh (sieve) size is specified as the number of pores on 1 inch. Example 100 mesh indicates 100 pores ...
