The company visited us in September, 2018. It was on campus placement for T1.
Round 1: Online Test
The test was hosted on Mettl. You can read up PrepInsta or any other such website regarding the questions generally on Mettl. There were 3 sections, for 90 mins total. Each section was not separated, so you could go back and forth between and you would have to manually manage time for each section. All sections included had a deadline of 90 mins.
Aptitude- Data Interpretation (Bar and Line Graphs), Percentage, Combinations?, This was really really easy. Just normal logical stuff. Don’t even remember it all because they are so easy ?
Verbal Ability and Reasoning – Spotting Errors, Ordering of Sentences, Sentence correction, Seating Arrangement, Direction Sense, Reading Comprehension
Technical- SQL. Majorly SQL. Read thoroughly. Queries and the theory stuff about Relational DBMS and Rollbacks. There were also a few related to Data Mining (OLAP, Star Schema, etc), DS (Max Heap, Arrays, Circular Linked Lists, etc)
