Job description doesn't align with current Role
I recently started a rotational program at a major Bank/FI. The job requirements mentioned I'd be working with the Big Data team and working with complex structure and unstructured data using various technologies/programming languages to deliver high quality work. They mentioned I'd work with the Big Data architects who'd guide me and help me out.
In the last 2 roles, I've done minor ETL and database work, but nothing related to Big Data or the technologies listed in the job description. I figured my 2nd role would include this exposure, but does not. I'm starting to think there was a big disconnect between HR and my Directors about the job requirements. I feel they've used Big Data and buzz terms to make the role enticing, but this is simply not the case.
I'm grateful for all the exposure to other business areas but a bit frustrated. I'm not sure what to do here, so looking for advice from many of the longtime professionals here.
How or what should I be doing do address this? There is a strong indication I can develop upwards into management based in past participants, so I'm not trying to burn bridges. Thanks!
