With more tech roles consistently dominating the workforce, computer science and IT have become one of the most popular and pivotal topics of study for students. As a result, enterprises and startups are always on the lookout for the best talent pool to fill their reputed tech roles. Moreover, a little hands-on experience on niche projects and technical certifications is nice-to-have while hiring freshers. Hence, hiring managers should always start from the alpha. In essence, irrespective of the job-specific role a candidate is being hired for, hiring managers should assess knowledge of the candidates on algorithms, data structures, and OOPS fundamentals. Here are few important and must-ask interview questions to assess the candidates’ knowledge of the fundamentals of computer science engineering.
