Recruitment and onboarding

How do you tell whether the problem is new hires leaving in the first few months or turnover after a longer period?

Turnover within two years is a different problem than people leaving after a longer period.

How should recruitment be set up so that only the candidate's juniority or seniority does not play a role?

In recruitment, juniority or seniority alone is not enough.

What should a job description look like: a precise list of tasks, or rather a framework for the role?

A job description can work more as a general framework than as a precise list of activities.

What role do communication and company culture play in onboarding new people?

Communication between teams and cultures belongs to company culture and influences employee onboarding.
