Free tool · no sign-up · 3 interview rounds
Generate AI-powered Tech Mahindra interview questions for all 3 rounds. Process: Aptitude → Technical + HR. Optimised for campus placements and fresher hiring.
From our curated bank of 10 Tech Mahindra-specific questions. The generator produces fresh AI-tailored questions each run.
What industries does Tech Mahindra specialise in and how does that shape interview questions?
Tip: Tech Mahindra is dominant in telecom (Vodafone, BT, AT&T clients), manufacturing, and BFSI. Interviewers may ask domain-specific questions — know what 5G, network slicing, or BSS/OSS systems are at a high level even as a fresher.
What is the difference between TCP and UDP? When would you prefer UDP over TCP?
Tip: TCP: connection-oriented, reliable, ordered delivery, flow control — use for web, email, file transfer. UDP: connectionless, best-effort, low latency — use for video streaming, VoIP, online gaming, DNS. Tech Mahindra's telecom projects make this a common question.
Explain the concept of graph data structure. What algorithms are used for graph traversal?
Tip: Graph: nodes (vertices) + edges. Directed vs undirected. Weighted vs unweighted. BFS (uses queue, finds shortest path in unweighted graphs), DFS (uses stack/recursion, finds connected components). Know adjacency matrix vs adjacency list representations.
What is a foreign key constraint and what happens if you delete a parent record that has child records?
Tip: By default, deleting a parent referenced by a child throws a foreign key violation error. Options: ON DELETE CASCADE (delete children automatically), ON DELETE SET NULL, ON DELETE RESTRICT. Choose based on business rules — cascade is dangerous in production without careful thought.
Write a function to check if two strings are anagrams of each other.
Tip: Sort both strings and compare — O(n log n). Or use a character frequency map — O(n) time, O(1) space (fixed 26-char alphabet). Handle edge cases: different lengths, case sensitivity, spaces.
