What This Training Covers

The Technical Interview Preparation programme at Tutorsbot spans 40+ hours across 6 structured modules. Every module is built around hands-on projects and real-world scenarios — not slide-heavy theory.

The curriculum is aligned with current Technology Training industry expectations and hiring patterns.

Enrollment & Training Quality

Technical Interview Preparation is available in 2 flexible learning modes — choose online live classes, classroom, hybrid, self-paced, or one-on-one depending on your schedule. Every batch is limited in size to ensure each learner receives personal attention, code-level feedback, and doubt resolution. Career support and certification are included with every enrolment. Tutorsbot instructors are working professionals who teach from delivery experience, and the training standard stays consistent across all modes and batches.

  • Arrays and dynamic arrays: insertion, deletion, access, and resizing complexity
  • Hash maps and hash sets: hash functions, collision resolution, and O(1) lookups
  • Linked lists: singly, doubly, and circular — insertion, deletion, and reversal
  • Stacks: LIFO operations, valid parentheses, and monotonic stack patterns
  • Queues and deques: BFS applications, sliding window maximum, and circular queue
  • Strings: immutability, string builders, anagram detection, and pattern matching
  • Choosing the right data structure: trade-offs between time and space for common tasks
  • Python vs JavaScript vs Java specific collection classes for interview contexts
  • Common gotchas: integer overflow, null pointer, and off-by-one errors in interviews
02

Arrays, Strings, and Sliding Window

10 topics

  • Two-pointer technique: pair sum, remove duplicates, container with most water
  • Sliding window fixed size: maximum sum subarray, average of k elements
  • Sliding window variable size: longest substring without repeating characters
  • Prefix sums: subarray sum equals k, range sum queries, and 2D prefix sums
  • Binary search on arrays: sorted array search, first/last position, and search in rotated
  • Sorting algorithms review: merge sort, quicksort, counting sort, and their complexity
  • Kadane's algorithm: maximum subarray sum in O(n) time
  • Matrix problems: spiral traversal, rotate image, and set matrix zeroes
  • String problems: longest palindromic substring, string compression, and zigzag conversion
  • Interval problems: merge intervals, insert interval, and meeting rooms
