May I ask what is meant by "tech consulting"? This is different to IT contract work I assume? Is consulting more about offering knowledge and guidance? What are the skills consultants need? Say a company wants to increase their organic search traffic, I'm guessing that's where a consultant can come in, do some research, provide recommendations, then build out a solution? And I guess to follow up on this, I've worked as an IT contractor for several years now, but I'm not clear how someone would get into consulting. I'm not even sure I've seen individual consultants before at companies. I've worked with Accenture consultants who have worked on projects with me, but I've never seen an individual do similar work. How would one get into this - is it purely networking, or do recruiters place consultants? Sorry if these are stupid questions. I guess I've never really understood what people meant by consulting and it seems people can use the term to mean quite a range of things.
