The general trend is that students do either competitive programming or development. Most students who do competitive program hardly work on any personal projects or open source as it is of almost zero value when it comes to campus placements. Companies like Flipkart, Morgan Stanely, Goldman, Amazon, Cisco etc conducts a competitive programming test as the first round in Universities. The remaining rounds are mostly data structures and algorithm/DBMS questions taken from GeeksForGeeks. Very few companies ask questions about development, personal projects, open source contributions etc. If a student does only development and hardly do any competitive programming it is very difficult for them to pass the first round.
