Online Coding Interview (Round 1):

• Duration: 80 minutes
• Number of coding problems: 3
• Difficulty: Medium
• Specific Coding Questions:
• "You are given an N x M integer matrix. Your task is to modify this matrix in place so that if any cell contains the value 0, then all cells in the same row and column as that cell should also be set to 0." (Set Matrix Zeros)
• "Longest Palindromic Substring"
• Another problem was mentioned but not detailed, possibly related to linked lists or arrays.
• The candidate also mentioned a coding problem about "A cycle occurs when a node's 'next' points back to a previous node in the list" with a duration of 20 minutes on 27 Oct 2023, which might be a separate assessment or part of a later stage.

Face-to-face Interview (Subsequent Rounds, leading to final rejection):

• This round was conducted on the college campus.
• Technical questions covered core subjects like OOPs, DBMS, Computer Networks, Operating Systems, Data Structures, Algorithms, Pointers, and Dynamic Programming.
• A basic HR question asked was: "What is the output of System.out.println(5 + "3"); ?"
• Other general HR questions included: "Tell me about yourself?", "Why do you want to work at this company?", "What values you can add to the company if we hire you?".

Overall Experience: The candidate was rejected in the final round because the role specifically required Android development proficiency, and the candidate was proficient only in Web Development.

Tips: Practice at least 300 questions, prepare core subjects thoroughly, keep applying on LinkedIn, make a single-page resume, include 2-3 relevant projects, and include relevant experiences.
