Just wanted to know if this is how you would solve this estimation question.

# Applicants = # Vacancies x (100 / Acceptance Rate)

# Vacancies = # Consultants / Typical Length of Employment

*****Fast Method*****

Assumptions

- # Consultants = 8000
- Typical Length of Stay = 4 years
- Acceptance Rate = 3%

# Vacancies = / 4 = 2000

# Applicants = 2000 x (100/3) = 67000 Applicants per Year

*****More Granular Method*****

3 Staff Levels (Junior, Mid and Senior)

Additional Assumptions

- % Junior Consultants = 60%
- # Junior Consultants = 4800
- Typical Length of Employment = 3 years
- Acceptance Rate = 3%

- % Mid-Level Consultants = 30%
- # Mid-Level Consultants = 2400
- Typical Length of Employment = 6 years
- Acceptance Rate = 10% (since fewer people apply for these roles)

- % Senior Consultants = 10%
- # Senior-Level Consultants = 800
- Typical Length of Employment = 10 years
- Acceptance Rate = 60% (since way fewer people apply for these roles)

# Junior Applicants = (4800/3) x (100/3) = 52,800 Applicants per Year

# Mid-Level Applicants = (2400/6) x (100/10) = 4000 Applicants per Year

# Senior Applicants = (800/10) x (100/60) = 132 Applicants per Year

Total = Around 57k applicants
