Deciding which skills are a must and which are simply nice to have will prove useful later. Managers who haven't nailed down these details often find they've hired the wrong people. Undoing hiring mistakes is expensive. It's better to make sure you know what you want from the start. Not paying sufficient attention to the search.
Communication is crucial.
You should be available when needed for meetings, interviews and questions. You want the right candidate. Help your search consultant or human resources professional do the job you are paying them to do. Many employees spend more time doing the job they're trying to hire someone else to do, instead of facilitating the search process. It's a misunderstanding of priorities.
