So basically,interviewer first gave his intro and also told me to give my intro,i did my projects on aiml so he said he aint well versed in that so he started with OS. in OS he asked me almost entirely every topic starting from RTOS(real time operating system function difference) to different scheduling algorithms,context switching,entire memory management,emphasized on demand paging and segmentation,asked basics of file handling.with every topic he used to give a usecase and use to ask which concept or how can we deal with the usecase and then he use to give followup .If you are pretty good in os it would be smooth.then he asked me linkedlist hard from striver reverse k group question he told me to code it in 10 mins and explain .. after that he asked 2 puzzles straight from gfg and also told me to generalize those puzzles into variable format.
