There were two stages:

1. First round was an MCQ test, where 20 questions on aptitude were asked in the first 30 minutes, and then 10 theory questions in the next 30 minutes. The theory portion was mostly from OS/DBMS, CompArch (technically not required), basic DSA, C, embedded C, and 8051 microcontroller.

I scored full in the theory portion and good in aptitude, to make it to the next round. Around 13 people made it to the interview round for the embedded software role.

1. Second round was a technical interview (no separate HR round) - it lasted approximately 30-45 minutes, depending on the person and panel.

First, I introduced myself and talked about my resume, where they asked me to explain my projects in short. Then 1-2 basic DSA programming questions were asked, which I wrote down the correct code for in a notepad in the first go. The remaining interview was mostly on fundamentals, OS/DBMS, memory, and C fundamentals, which I mostly got correct.

The interviewer seemed like he wanted to end the interview in a hurry, so I tried to buy some more time by talking a bit about what type of work and tech stack I would be using during my time at Texas, and related stuff.

MCQ round - Questions related to DSA, OS/DBMS basics, memory, space/time complexities, arrays, pointers, assembly code, binary tree, and cache.

Interview - Writing the code for matrices multiplication in C, explaining the difference between virtual memory and physical memory in detail, basic differences between microcontrollers and microprocessors, cache memory explained in detail, C fundamentals and sizes of data types, etc.
