first they introduce themselves and asked me for a intro, then they asked 2 dsa questions.. q1) merge intervals from leetcode. they said me to open leetcode and search this problem and solve it. q2) they give a link of neetcode problem.. it was find minimum in rotated sorted array.

after that they asked questions from os, scheduling algorithms, deadlock conditions, RISC vs CISC, journey of a program - like how the compiler execute it, and some memory management questions..

this round goes well and I was selected for the next round.

this round is totally based on my resume and discussion about the job role.. they asked me to explain my project in detail, as I have a live link of my project, they opened it and start asking questions from the site, like what is this, why this, then they asked me to write a sql query as I was using it in my project. then they asked me - do you know about automation? can you write i2c driver code... then they asked many ml and dl basic questions like bias variance tradeoff, vanishing and exploding gradient, rnn, lstm, transformer architecture, resnet -- as such keywords are there in my resume.. then they explain the job role in detail.

for interview prepare linkedlists, stack, binary search, bit manipulations specially.. don't forget to prepare cs fundamentals in depth, as qualcomm loves os, oops, coa..
