If it helps expedite the process of getting an offer, I would go for it. I will not consider it if coaching starts to feel more like a detour than a straight line to getting a job, especially when I am "overdue" for a new job. However, there's also the issue of cost. I only have a few hundred dollars on my account, and life coaching seems too costly to sink into if I go on more meetings.
Job interviews have a great variety. It could be that the variety of job interviews, at least locally, does not easily extend to fit people with my personality type. But I do not consider myself to be one-of-a-kind. I know there are many more like me. I want to find that niche that people like me fit into.
