Wrote a Blog Post
Having worked in three different early-stage startups as a product engineer. I have collaborated and mentored with various interns. Throught my experience I have seen most of them facing some common issues when they start working in teams, especially  in fast paced environment where every PR is reviewed.  So I decided to write a blog that would help such people with some insights as to what they can learn that may help them smoothly transition.
