Start with the end objective in mind. You can divide the questionnaire into four sections:
1. Pre-interview:
- Access to vacancy information (e.g., portal, company website)
- Clear job description and eligibility criteria
2. At interview:
- Convenience of place and time
- Various forms and information asked from candidates
- Feedback on security, reception, and time taken in attending the candidate
- Information shared in case of delay and total time taken for the whole process
- Number of interview rounds and follow-up
3. During the interview:
- How the panel treated the candidates
- Nature of questions asked
- Handling of candidate queries
4. Post-interview:
- Time between joining and initial induction
- Offer process, negotiation, joining time, and required documents
- Experience on the induction day
- Availability of work desk, mail ID, and other necessary infrastructure
- Perception of company culture, policies, communication, and alignment of job profile with actual work
I suggest creating an initial draft and then seeking feedback from your senior colleagues at the office. Ensure the questionnaire is not overly cumbersome.
