Technical Coding
First round technical discussion. Had a teams call scheduled for an hour. The interviewer didn't turned on his video and asked me to share the screen and turn on the video. This made the interaction feel impersonal. Asked some questions on LinkedList, Interfaces, and most of the questions on data base queries. The interviewer was mostly focused on syntax level knowledge. The perception that I got after taking the interview was that this is not the kind of company I would like to join. Based on the interview experience, I did not get a positive impression of the company. The technical assessment methods seemed outdated, focusing excessively on rote memorization rather than evaluating a candidate’s overall competencies and problem-solving skills.

Technical Coding Behavioral
It starts with submitting your application online, making sure your resume and cover letter are tailored. Then your resume gets screened to check your qualifications. Some companies have an online assessment (OA) to test your skills. For tech roles, there might be a hackathon or coding challenge to see your problem-solving and coding skills. After that, you might have a phone or initial interview to talk about your background and why you're applying. Next are the technical interview rounds where you'll solve coding problems, discuss algorithms, and show your technical knowledge. Then you'll have a managerial or team interview to see if you fit culturally and can work in a team. An HR interview usually follows to check your soft skills and cultural fit. Some places use assessment centers for group activities and real-life scenarios to evaluate leadership and communication. Lastly, there might be a final interview with a senior person to discuss strategy.

Quoted word for word from Commvault interview reports.
“Given a binary tree, remove nodes outside the range [min, max] and return the post-order traversal.”
Read reports →“Given a number p, find the smallest integer greater than p whose binary representation does not contain '11'.”
Read reports →“Given a number n, find the total count of n-digit binary numbers that contain two consecutive 1s. For example, if n=3, the 3-digit binary numbers are 000, 001, 010, 100, 101, 110, 111. Among these, only 110 and 111 have consecutive 1s, so the answer is 2.”
Read reports →“Given n and k, count the number of arrays of size n where the element at index i+1 is at least twice the element at index i.”
Read reports →“What is the next greatest number that does not have consecutive 1s in its binary form?”
Read report →“Write a recursive function to reverse a stack implemented using a linked list, given push, pop, and isEmpty functions. No loops are allowed.”
Read report →“Considering a bag with coins of different types, represented by an array a[i] indicating the count of each type, what's the minimum number of coins you need to withdraw to ensure you have at least 5 of each type? Each withdrawal is one coin, and you only discover its type after picking it. If it's impossible, return -1.”
