LFH Answers Tech Mahindra such assessment is the Logical and Functional Assessment LFH Answers Tech Mahindra.
LFH Answers Tech Mahindra
LFH Answers Tech Mahindra or Logical and Functional Assessment is an online test conducted by Tech Mahindra to evaluate the logical reasoning, problem solving and functional skills of candidates. It consists of around 50-60 questions to be answered in 60 minutes.
Sections in the LFH assessment
The LFH assessment has the following sections:
Logical Reasoning
This section tests the ability to think logically and solve problems using logic. Questions may include puzzles, sequences, analogies, deductions etc.
Coding
Candidates may be asked to read code snippets in languages like Python, Java, C++ etc. and answer questions related to output, syntax, logic etc.
Database
Questions to test knowledge of basic database concepts like tables, keys, queries, joins etc.
Operating Systems
Fundamental concepts related to operating systems like processes, memory management, files & directories, user interface etc.
General Questions
Miscellanous questions from general topics like algorithms, data structures, computer networks etc.
Sample Questions
Here are some sample questions from previous LFH assessments:
