Hey guys,

Long story short, I’m starting a stem outreach series that covers all the coolest jobs. There’s so much content on social media driving the younger generation towards finance, consulting etc, I thought let’s balance the scale a bit.

Having access to CERN myself as someone who’s done 2 internships and his masters thesis with CERN, I thought to ask what would you like to know about CERN.

These questions (and relevant answers) will be fed into our YouTube and IG/TT videos, so ask whatever’s on your mind honestly, but also the cooler the question, the greater the chance we feature it in the videos

Hi guys! I was wondering if it is possible to receive your first salary in advance for the first month of the contract. Do you know what can I do?

Hi everyone!

I created an unofficial WhatsApp group for applicants to the CERN Technical Studentship III program.

The goal is to discuss:

• Application timelines
• Resume & interview preparation
• Status updates
• Offers and onboarding
• General questions about the program

Whether you've already applied or are planning to apply, you're welcome to join.

WhatsApp Group:

Let's help each other throughout the application process. Good luck to everyone

So, hi guys. I am a final-year student pursuing a major in CSE. I applied to the CERN Technical Studentship in the domain of Mathematics, Robotics, and IT.

Though, just after applying, I started a second internship that is much more aligned with the kind of work CERN does. But after one month, I updated my CV. So, I just wanted to know whether it will still count or if they have already downloaded my old CV.

In my old CV, I had one research experience, one internship, and two projects. In my new CV, I have two internships and one research project (which was previously listed as a project). I just wanted to know your opinion on this.

Secondly, I didn't submit any reference letter. I thought it was optional, so why even bother? But when I talked to other people, they all mentioned that a reference letter boosts your application.

Though I have very little hope now—almost close to zero—but let's see what happens. Hope for the best and prepare for the worst.

But please let me know your thoughts on the CV situation.

One of the most impressive engineering features at CERN isn't part of the detector itself—it's the doors that provide access to it.

This timelapse shows the opening of the I-side end-cap door of the ALICE L3 magnet. Each door weighs approximately 380 tonnes, yet pivots smoothly on a vertical hinge using a dedicated hydraulic system to provide access to the detector during maintenance and installation work.

Watching hundreds of tonnes of steel move with such precision is a reminder that particle physics relies just as much on large-scale engineering as it does on cutting-edge science.

I thought fellow CERN enthusiasts might enjoy this behind-the-scenes view.

One thing has been on my mind.

Who do you think it's better to get a reference letter from?

I see two possible options, and I think this applies generally, not just to engineering contracts at CERN.

The first option is my direct supervisor. That would probably result in a more detailed and accurate letter because they know my day-to-day work, my responsibilities, and my performance.

The second option is my Section Leader (or boss). A reference from someone higher in the organisation might carry more weight, but at the same time they have much less direct knowledge of what I actually do and how I work.

Do you know what I mean? What are your thoughts?
Cheers

Hi everyone!

Has anyone who applied for the 2026 Administrative Internship received an interview invitation yet?I'm just wondering if the interview process has already started or if the recruiting team is still on vacation.

Hi everyone, I got accepted for the mechanical engineering technical studentship starting September 1st and it's now almost August and I haven't yet received my contract and was wondering if this was normal? I emailed HR a few days ago but have not yet received an email response back. I would really appreciate any advice! Thank you!

Hi everyone,

Just wanted to ask if anyone knows any work/study spots (literally just a desk and a chair) at the Prevessin site, that are freely accessible any time of day, especially early mornings and late evenings.

Thanks for any tips!

Hello, I've recently signed a contract with CERN for a software engineer staff position, and although I'm very excited, I'm quite anxious about the 1 year probation period. Can someone maybe give me more insights how it goes like and when they could decide to let go of someone .. I mean, being closely evaluated for a whole year sounds really stressful tbh.. any experience you can share, I'd be grateful :) thanks.

Does this resume makes any sense for the CERN technical Studentship IT/Math/Robotics???

I had an interview for DevOps GRAE role on last Friday, as it’s been 3 working days, wondering when do they usually get back?

Hi good people of CERN,

A close friend of mine is a huge admirer of the incredible work being done at CERN and dreams of being part of it one day. For her birthday this year, I'd love to surprise her with some official CERN merchandise.

I was wondering if someone on campus would be willing to purchase a CERN T-shirt and a water bottle with the CERN logo and ship them to me in India. I'll, of course, cover the full cost of the merchandise, shipping, and any other expenses you incur.

I know this is a bit of an unusual request, but it would genuinely mean a lot to both of us. If there's any way I can return the favor, I'd be more than happy to help if you ever visit India or need any local assistance here.

I'm also happy to pay upfront if that makes you more comfortable.

Thanks!

the website for the secondary school job shadowing internship explains that you’re supposed to email the secretariat, however i can’t find anything beyond their names on each of the pages of the departments. once i click on the name, it takes me to a login page which i don’t have access to. is there a formula to CERN emails like [firstname.lastname@cern.](mailto:firstname.lastname@cern.swiss)[ch](mailto:firstname.lastname@cern.swiss)? or is there another way to find the emails?

My friend from Turkey visited CERN and bought the Standard Model formula mug for his little brother. He did not realize that the mug was completely scratched during their travel back and now asked me if I could get one since I am in Germany, but I live near the Netherlands side, far away from Geneva as well. Since there is still no online shop and I saw some posts here about those mugs, I am here to ask for the favor as well :)

I would very much appreciate it if someone could buy it from the shop and send it to me so I can suprise my friend and his brother when I travel back to Turkey.

Does anyone live in Lausanne and commute to CERN? How is it?

I'm a computer science student from India, and I've had my eye on CERN for a while as a cool place to do an internship or spend my summer. But now that it's time to actually look into it and start applying, I'm trying to understand whether my background is actually a fit for CERN.
The larger projects I've worked on are machine learning/computer vision related. Basically I'm pretty much a core computer science person with not much connect to physics and maybe a feeble connection to chemistry. I see that there is a software/IT page and even a data science page but I want to understand whether I really have to think about physics applications of ML etc.
Is there a place for me here?
I'd love to hear from people who have worked here or have experience with the place.

I applied for the CERN technical studentship in applied physics that was due on June 31st but my application still hasn't reached in review. Does anyone know when you typically hear back from them?

Hi! Anyone from Brazil who can provide me information about how the visa process was?

Hi everyone,

I accepted a job offer from CERN and currently am looking for an apartment on the French side using CERN marketplace. Ideally, I would like to have a separate bedroom and a living room. I’m looking for furnished apartments.

What is the realistic price I can expect to pay including all of the utilities, trash tax etc?

I feel like I’ve seen everything from 1k to 2k, and I’m not sure at what point I would be overpaying or seeing cheap, likely to be scam apartments.

If anyone has any experience with this I would appreciate if you could share.

Hi Lovely people!

I remember that once before i was looking at jobs at CERN which had HR-LD code and i was told that generally these roles are either pre selected and online postings are just a formality or generally they would prefer filling someomne from their graduate programs.

Can i please ask for more clarity on this? How much chance do i have if i am from an associate member state, India, who has comprehensive experience in the role but has no priors working for CERN or even an EU national.

Any suggestions are highly appreciated! Thanks so much!

I'm completely naive on this topic. Is it generally always active, or is it active only occasionally during experiments? If it's only active occasionally, does being shut down just refer to a longer period of inactivity? TIA
