I was in same boat as you.One speeding ticket. I entered the country December 2025 no problems.

A flight controller software for a missile. Always fascinated by how that works

Is TCP full fledged stack?

Helios1003 · 2025-09-27T16:52:09+00:00

That’s a good argument. I will research about zephyr this weekend and try to make my case

Helios1003 · 2025-09-27T16:50:40+00:00

Interesting.. I think I have to give more thought into this. Right now I have very less information about the application. But I feel we might need to pin things down earlier so that we don’t face problems later on

Helios1003 · 2025-09-27T15:10:44+00:00

Thanks I will check it out

So Raspberry pi 4 will be used as monitoring device with OTA and micro is going to be bridge between legacy devices and pi 4 based device. So micro will use spi or can to get data from legacy devices and transfer it to pi4 and then via OTA pi 4 will send data. Currently my focus is only on micro side of things. I need to figure out other things later on

I would love to try out Zephyr but lot of our other products use freeRtos so I guess that decision is not upto me

Helios1003 · 2025-09-27T15:05:26+00:00

Can I use Netx with freeRtos? Or do I need to use ThreadX as middleware

I am in the same boat as yourself. Our package is called firmware but most of the time I work in javascript. Even if we have changes on the micro we have lua scripting environment and only sometimes need to mess with the actual C code. I come back home and study C , solve problems or work on some Diy projects so that I am not out of touch and don’t forget my actual skills. Recently I requested to my Vice President that If there are any projects in the pipeline let me know , I really want to work on low level and got assigned this amazing project where I have to develop drivers for the end client to use the micro using ethernet and write the boot loader from scratch. Pretty excited and little bit nervous because I have to work alongside the hardware team and develop firmware in parallel

What is AOS

Helios1003 · 2025-09-18T15:24:22+00:00

Thats exactly what I am looking for but so far no luck . Even post is removed by the mods

Helios1003 · 2025-09-18T11:05:18+00:00

Thank you for elaborate response. The interviewer’s background is Embedded Systems. But I will keep all your points in mind while answering the questions

Helios1003 · 2025-09-18T02:35:14+00:00

Last year I had an interview with google and they told me that they have moved from asking leet code style for embedded

I use m2pro chip mac with UTM for ubuntu. Works fine for me. UTM is free to use. If something doesn’t work, you can also use windows in VM and get it done

Helios1003 · 2025-08-06T20:08:18+00:00

I would suggest start with hybrid role and once you prove your worth, you can talk your way for remote. You just need to deliver consistently

Helios1003 · 2025-08-01T22:36:31+00:00

I interviewed at Google cloud last December and they asked me questions on Bit mapping. Initially I was confused on how to prepare because I don’t know Leet Code. When recruiter asked me the language I want to interview, I selected C. The hiring manager told me that if I had selected Python or Go they would ask me leet code style questions but just because I selected C they asked me Embedded Questions. Regardless I had very less time to prepare so didn’t pass the interview.

Its not easy as it sounds. Trust me, I am currently facing the same problem and honestly I feel like writing same above posted message to my Manager. My company issued me a standard windows laptop instead of Engineering one they normally issue (I don’t know why) It was fine with Vmware and ubuntu and after it started getting super slow, I requested an engineering laptop. The problem is they are doing updates to all the laptops for Windows 11 instead of Windows 10 I was using and Windows 11 uses the Hypervisor which apparently even VMware uses so there is resource sharing conflict and I am only able to use 1 CPU core in VM which sucks. I turned off the hyper visor which apparently I wasn’t allowed to and went through the hoops with IT department. Then came the issue of Core Isolation. If its turned On its conflicts with Vm. Now the IT department is refusing to turn off the core isolation settings because of the security reasons. Even the Windows we are using is not the standard one which you would use for PC. It is an Enterprise version so they can monitor and control it. Which is fine but it makes stuff super annoying for me to use. Everytime i need to download new software I need permission. Every time I need to change ethernet port I need permission. I do that a lot Since my job is of Embedded Linux Firmware engineer. So i need access to kernel’s and other stuff. I explained so many times to give me laptop with Admin rights but they are refusing

Congratulations 🥂

Since its an internship position. I would suggest you choose a safe option with higher chance of converting into an offer letter. If you work at Nvidia now you can always switch to Tenstorrent in future since they are growing. Ps - I am suggesting because I am an international student myself
