IT job interview questions and answers
Got your interview date? Don't panic. The questions boards ask are fairly predictable, and this is that list — sorted by subject, each one with what to say when it comes up. Pick the topic your interview is about.
17 topics · 224 questions
Programming languagesProgramming language interview questionsAlmost every IT interview opens with language questions — which one you prefer, why, and how you choose. Here is what your answer needs to cover.
CodingCoding interview questions and practice problemsThe hands-on problems boards actually set — arrays, strings, matrices — each with a worked example to try yourself.
Data structuresData structure and algorithm interview questionsLinked lists, trees, graphs, sorting and dynamic programming — the problems that come round on almost every board.
PythonPython interview questions and answersFrom data types to decorators, generators and pandas — the questions asked most often for Python roles.
JavaJava interview questions and answersThe four pillars of OOP, inheritance, polymorphism, threading and garbage collection — the compulsory questions for Java roles.
JavaScriptJavaScript interview questions and answersvar/let/const, closures, prototypes, async and the DOM — what a front-end role will certainly ask you.
PHPPHP interview questions and answersVariables, arrays, sessions, OOP, PDO and file uploads — the PHP questions for web developer roles.
C++C++ interview questions and answersPolymorphism, constructors, friend functions, templates and the STL — questions for software and systems roles.Code reviewCode review interview questions and answersWhat a review looks for, what makes a good reviewer, and how you fix bugs — the questions about working in a team.OptimisationOptimisation and complexity interview questionsTime and space complexity, Big O notation, caching, memory leaks and parallel processing.DatabaseDatabase interview questions and answersSQL versus NoSQL, keys, normalisation, indexes, JOINs, transactions and ACID — compulsory for any developer role.NetworkingNetworking interview questions and answersThe OSI and TCP/IP models, IP addressing, subnetting, DNS, firewalls, NAT and VLANs.Software developmentSoftware development interview questions and answersOOP, design patterns, the SDLC, Agile, version control, TDD, ORMs and REST APIs.Operating systemsOperating system interview questions and answersProcesses and threads, context switching, deadlock, virtual memory, paging, file systems and system calls.BehaviouralBehavioural interview questions and how to answer themDeadlines, teamwork, owning a mistake and setting priorities — the questions that test conduct rather than knowledge.Problem solvingProblem-solving and logical interview questionsArrays, linked lists, trees, graphs and design patterns — the questions that test how you think.IQ and puzzlesIQ and logic puzzles — interview questions with answersHandshakes, burning ropes, the river crossing, Monty Hall — the puzzles IT boards set, with their solutions.Every question here comes from TalhaTraining's own collection, put together by instructors who work in the industry.
