Experience:

This experience details the interview process for a Technology Analyst Intern position at Citi Bank (Citi CSC) during an on-campus drive for pre-final year students.

1. Online Test (September 12, 2021): The test was video proctored and consisted of 5 sections with sectional timers. There was no negative marking.

• CS subjects' based MCQs (25 Questions in 35 minutes): Questions covered stacks, queues, trees, searching, sorting techniques, output prediction, and OOPS. Basics were important.
• Aptitude (16 Questions in 16 minutes): MCQs on topics like work and time, probability, permutations and combinations, percentages, ages, profit and loss. Questions were doable but required speed.
• Logical Reasoning (14 Questions in 14 minutes): Questions were of easy to moderate level.
• Verbal Reasoning (22 Questions in 18 minutes): Covered antonyms, synonyms, prepositions, and passages. Questions were easy, with tips to read passages carefully.
• Coding section (2 Questions in 60 minutes):
  1. Trapezium Pattern Printing (Passed 11/11 test cases).
  2. Rat in a Maze (Backtracking approach, passed 25/32 test cases).

40 students were shortlisted for the interviews after this round.

2. Technical Interview (September 15, 2021): This 20-minute interview was conducted on Zoom. The interviewer was friendly and started with an introduction and "Tell me about yourself." Questions were based on the resume, including a self-rating in Java (candidate rated 6/10). HTML concepts (what it is, what was learned, what happens when entering text in a text field) were discussed. The candidate explained a project using the STAR approach. Questions on data structures (arrays, strings, trees, linked list, stacks, queues) were asked, followed by a DSA question where the candidate provided two approaches (better and optimal) but was not asked to code.

3. HR Interview (September 15, 2021): Details of this round were not explicitly provided in the snippet, but it's mentioned as the final round.
