Recently I spoke with Dinesh Nayak about his journey from being an IT professional to a Risk modelling quant. I asked him a couple of questions about his background and how he managed to get into risk modelling. Hope this is helpful to some of you that are interested to switch career to Credit risk modelling.
Until recently Dinesh worked as an IT Engineer for a service based IT company. After hearing from a friend about career in Risk Modelling, he started exploring career opportunities in this field. He contacted me some time last year (in Nov). I advised him to focus on the basics and complete my credit risk modelling course. He sincerely did the course and also clarified his doubts over a couple of calls with me. It gives me pleasure to say that he has managed to clear interviews at so many places (top notch companies such as KPMG, JPMC, EY).
Enjoy the below (rather short) conversation with Dinesh. For anything, reach out to me over email.
