Selected Interview preparation journey
Journey
I was introduced to programming back in school but I wasn't that passionate about it. Started programming again in college when I was sophomore. Went on to secure open-source internships. Then I applied to several companies specially open-source companies and secured an internship and full-time SDE offer at Red Hat.
Application story
I came across a link to express my interest to intern at Red Hat. Once I expressed my interest, I was given a link which contained a time-bound coding test containing 3 questions.
