Ways of revealing internal psychological processes of candidates / employees (how responses of candidates / employees to your questions will show the seriousness of their intentions and reliability).
The first way is the consistency of “think-say-do” in the candidate’s / employee’s speech. For example, a person thinks, says, and does the same thing, for instance, sends a CV, participates in a telephone interview, executes the agreed tasks, comes to the interview at the appointed time, gets a job, and achieves set / agreed objectives. If the candidate cannot come, then they call and / or write, arrange for another day and / or time. If something changes in their thoughts, decisions or behaviour, it goes to the level of communication and coordination with those who they have an agreement with.
