I was interviewed in Dec 2020.
Round duration - 70 Minutes
Round difficulty - Medium
There were 5 people in the zoom meet, including me. Rest all 4 were interviewers, 3 from India and 1 from the United Kingdom.
They started with my introduction and then moved on to the questions from my resume, starting with my internship at Samsung Bangalore and then projects.
Then another interviewer asked about my weakness and strength. Then comes the turn of coding questions.
Starting with finding the minimum element in O(1) time, rotating the 2-D array by 90 degrees, OOPS questions were also asked like- polymorphism, abstraction, virtual class. Some OS questions were- cache, paging algorithms.
Then come my POR and other activities.

Page replacement algorithms are used in operating systems to decide which page to replace when a new page needs to be brought in.
FIFO (First In, First Out) - replaces the oldest page in memory
LRU (Least Recently Used) - replaces the page that has not been used for the longest time
LFU (Least Frequently Used) - replaces the page that has been used the least number of times
Optimal - replaces the page that will not be used

Normal DP question (LC med)
I was interviewed in Dec 2020.
Round duration - 120 minutes
Round difficulty - Hard
There was 2 parts. First part problems were based on Quantitative Aptitude. Problems were of 3 types- Easy, Medium and Hard with different scores. Difficulty keeps on increasing if you answer correctly and keeps on decreasing if you answer incorrectly.
First part was of 45 mins.
Second part consisted of 2 coding problems- Medium, Hard. One was based on Greedy and other was a difficult DP + Bitmask problem.
Coding part had more weightage than Aptitude.

Determine if a given string can be converted into a 'Beautiful String' using a specific operation.
Check if the input string is already a 'Beautiful String' by checking if it contains 'abc' in the correct positions.
If 'abc' is present in the input string, check if the left and right portions satisfy the defined conditions.
If the conditions are met, return 'True', otherwise return 'False'.
Round duration - 90 minutes
Round difficulty - Medium
There were 3 interviewers in my panel. The most senior panellist asked q. related to my interests and internship experience.
Other 2 asked questions related to Coding and subjects. There was 1 coding question which was implementation based and involved many corner cases. They were checking if I was able to figure out different corner cases and handle those.
There were situation based questions also asked. One question was on system design of Arogya Setu App.
Calculate the product of two complex numbers represented as strings in the form “A+Bi”. Here, ‘A’ represents the real part, and ‘B’ represents the imaginary part.
Calculate the product of two complex numbers represented as strings in the form 'A+Bi'.
Parse the input strings to extract real and imaginary parts of both complex numbers
Perform multiplication of the complex numbers using the formula (a+bi)*(c+di) = (ac - bd) + (ad + bc)i
Format the result as a string in the form 'A+Bi' and return
Round duration - 30 minutes
