Some of the inputs are purely my experience working across multiple companies from big retailers to desi unicorns. So pls take this as a data point only -
#1 In terms of compensation growth, product is exciting relative to sales. I have my batchmates across sales, ops, marketing and consulting. It may be due to supply/demand constraints, not sure how it will pan out going forward. My personal take on learnings is - In sales you learn dhanda, get the macro picture whereas in product you are still protected but many companies are putting growth numbers as KPI on PMs as well, still field knowledge would be missing.
