1. Aptitude

This section consisted of several sub-sections like Logical Reasoning, Attention to Detail, etc. with different time limits for each of the sub-sections. My advice to crack this round will be not to stick and waste time on a single question but instead, try to solve other questions because of the constrained time limits.

2. Programming Ability

This section had algorithm design questions that were in the form of a flow chart with different steps to complete the algorithm stated in them and some blank spaces in between to be filled by us. Basic knowledge in algorithm design and a little reasoning can help solve these kinds of questions. This round had MCQ questions that focused mostly on TREE data structure with multiple questions on traversals and AVL TREE insertions and deletions. My advice will be to study the TREE data structure properly to gain some advantage in this section.

3. SQL

This section entirely focused on questions related to SQL queries, syntaxes, aggregate functions, and DBMS concepts. My advice will be to have enough practice on SQL.
