Is this the correct use of the semicolon?

Yes, a colon preceeds a list.

Yes, looks fine. It allows each of the “experience” items to be further sub-divided by commas without muddling the organization of the sentence.

Oh, wait. You were asking about the semi-colon. Yes, you use them to keep independent clauses together.

A colon is very formal. A semi colon is semi-formal; it is used, like here, to separate two disctinct thoughts in the sentence. Where you might normally use a – informally.

Thanks for all the input!

I am curious why your question used a colon; your question was about a semicolon.

If I were writing your sentence, I would use a semi-colon after “sales force automation”. If “sales force automation” is paired with “call center operations”, then don’t use a semi-colon there, but add the word “and” .

I would not use the colon. I would use a comma after “marketing and sales” and before “including”.
