I applied online. The process took 1 week. I interviewed at HackerEarth (Bengaluru) in Jan 2021
Interview
Online test followed by 4 virtual F2F interviews. Difficulty for problem solving DS/Algo questions are of easy level, healthy discussion in case of design questions. For most of the problem solving question, we also have to write clean code for the same too.
Round 2,3,4: Virtual F2F Interview Round, 2 questions were asked in each round, first for testing coding skills, questions were easy based on basic DS/Algo, arrays being the favourite, second question was to test designing skills. Be prepared to get grilled on designing questions.
Round 5: VP Technology took the interview. Pattern was same as of previous interview rounds, but the difficulty was little higher. Coding question was on strings.
