I had a call with Karun regarding Data Science Career Guidance, and it was a great interaction with him. I gained valuable insights about the improvements required in my resume, job applications, and how to better prepare myself for the industry. Most importantly, Karun provided me with an overview of the actual industry-level responsibilities of a data scientist, which was extremely valuable. Thank you, Karun, for your guidance and support.
