Before joining, ensure the company gives effective and systematic training. Don’t be carried away or misled by the ads. Ads always make sky-high claims.

Find some time to contact a few transcriptionists who were trained and are employed in the company where you intend to get trained. Beware of any biased feedback. If majority of them give positive response, go ahead.
