And what about the Limitless Pendant? - URL: https://www.lordofthesmartrings.com/job-interview-vs-oura-garmin-and-whoop-limitless-pendant-stress/ - Published: 2025-11-12T09:50:21.000Z - Updated: 2025-11-12T09:50:21.000Z - Description: I arrived at the interview wearing my wearables – Garmin, Whoop, Oura, and the AI pendant Limitless. All detected stress, each differently. The highest peak? Garmin: 99/100 right in the middle of the talk. Which one told the truth? And what does the LLM say? - Author: LORDoftheSMARTRINGS - Tags: stress, 💍Oura Ring Gen 3 & 4 & 5, Whoop, Garmin Fenix 8 It was an ordinary Tuesday at 2:30 p.m., and after years, I was heading to a job interview again. Across from me sat the department head, an HR recruiter, and the HR director—a bit of an overmatch. Even though I’m no rookie, interviews can still bring a dose of stress. During the interview, I was wearing representatives from the main wearable categories: - ⌚ **Garmin Fenix 8** - 📏 **Whoop MG** - 💍 **Oura 4** - …and as a bonus, my personal AI assistant – ☮️ **Limitless Pendant** The question is: did these devices detect the stress? And, more importantly—**how accurately?** Before we dive into the data, let’s mix a quick anti-stress cocktail. Cheers! 🍸 📽️ Prefer video version?

So I decided to prepare not only mentally, but also **physiologically**. About an hour and a half beforehand, I took a few mindful steps: - 🫁 **Physiological sigh** – A technique recently popularized by Andrew Huberman. The idea is simple: take a deep inhale through the nose, add a small “top-up” breath (just when you think your lungs are full), and then exhale slowly through the mouth. A few rounds of this can calm the nervous system almost instantly. I felt clearer, more focused, and grounded. - 💊 **L-theanine** – An amino acid found in tea that promotes calm focus without making you drowsy. I often take it before situations where I want to be in **flow** yet stay relaxed.

For me, methylene blue helps me feel a little less antisocial (sounds odd, I know, but it works). In small doses, it has a mild nootropic effect and seems to sharpen my verbal interactions.

Did it help? At least as a placebo, yes. 😄 But I think the whole ritual really put me in the right state of mind. In reality, it’s hard to say for sure — unfortunately, I didn’t have a control group without the cocktail. :) --- ## 📊 **What Do the Data Say?** The interview went by quickly — 45 minutes and it was all done. I had a decent flow, good word cadence, and probably a lively heart rate too. ### ⌚ **Garmin Fenix 8 – Orange Peaks of Truth** Garmin shows stress levels on a daily graph using color codes: - 🔵 **Blue** \= Rest (9h 29m) – including sleep - 🟠 **Orange** \= Moderate to high stress - ⚪ **Gray** \= Physical activity The highest peak appeared around **2:42–2:45 p.m.**, climbing all the way up to **99** — dangerously close to the maximum value of 100\. And the timing? Right in the middle of the interview. Coincidence? Hardly! ![](https://storage.ghost.io/c/01/ca/01ca9f1d-13b0-43d5-a8fe-dac2f7d3dc2f/content/images/2025/11/1BF40D23-7076-4655-8C8C-FAC38BD5AFAC_1_201_a.jpeg) Garmin and Stress interpretation [GARMIN FENIX 8](https://amzn.to/40zsCVV?ref=lordofthesmartrings.com) ## 📏 **Whoop MG – The High-Stress Zone** Whoop visualizes stress a bit differently. Instead of a continuous minute-by-minute graph, its **Stress Monitor** looks more like a **tachometer**, showing your current stress load on a scale from **0.0 to 3.0**. [Whoop 5 / MG – is it worth the money? \[Review\]A slightly different take on a review of the screenless fitness tracker Whoop. What drew me to it, and what put me off?

Heads-up: this is going to be a long review — but I believe it’s worth your time.![](https://storage.ghost.io/c/01/ca/01ca9f1d-13b0-43d5-a8fe-dac2f7d3dc2f/content/images/icon/favicon-31.ico)LordOfTheSmartRingsLORDoftheSMARTRINGS![](https://storage.ghost.io/c/01/ca/01ca9f1d-13b0-43d5-a8fe-dac2f7d3dc2f/content/images/thumbnail/WHOOP-MG-review.png)](https://www.lordofthesmartrings.com/whoop-5-mg-is-it-worth-the-money-review/) Whoop’s measurement was more consistent — it marked **the entire period from 2:14 p.m.** (right when I sat down in the meeting room and started strategizing) **until 3:51 p.m.**, when I finally got into my car and put on some **Sabaton** to calm down. In other words, Whoop also captured the **afterglow of the stress response** — which actually makes sense. Stress often peaks *after* a stressful event ends, as the nervous system needs some time to normalize. According to Whoop, I spent **3 hours and 44 minutes** in the high-stress zone that day. For comparison: my six-month average is **2 hours and 18 minutes** — so this interview day clocked in **almost 90 minutes higher than usual.** ![](https://www.fitnesator.cz/content/images/2025/10/image-2-1.png) Whoop and its stress interpretation [![CTA Image](https://www.fitnesator.cz/content/images/2025/05/Announcement-post-HEADER-1800x1000.jpg.webp)](https://fitnesator.link/whoop?ref=lordofthesmartrings.com) Whoop 1 month free.

On my way to the interview, I ran into an unexpected **traffic jam**, which added a little *bonus round of nervousness*. I’d definitely classify that period as “stressed.” ![](https://www.fitnesator.cz/content/images/2025/10/518581DC-DE3D-4F58-8AC5-D06A15EFB6D4_1_201_a.jpeg) Oura ring and Daytime stress [Oura ring 4 on AMAZON](https://amzn.to/4nBkU6s?ref=lordofthesmartrings.com) ## I**n Conclusion** All three devices flagged the more nerve-wracking parts of the day as **stress** — though each used a different method of interpretation and visualization. **Garmin**, with its precisely structured and highly granular orange “report card,” showed values right at the edge of the maximum. Personally, I’m not a big fan of that type of graph — I tend to prefer a more **high-level view**, which **Whoop**delivers nicely through its simple curve and tachometer-style stress scale from 0 to 3. **Oura**, on the other hand, approaches stress from a slightly different angle — one that aligns with the philosophy of Elissa Epel, the author of *“T*[*he Stress Prescription.*](https://amzn.to/49wj5UP?ref=lordofthesmartrings.com)*”* It divides mental states into four distinct zones: ![](https://storage.ghost.io/c/01/ca/01ca9f1d-13b0-43d5-a8fe-dac2f7d3dc2f/content/images/2025/11/CleanShot-2025-11-04-at-12.43.26@2x.png) [The Stress Prescription](https://amzn.to/49wj5UP?ref=lordofthesmartrings.com) It’s no coincidence that **Elissa Epel** is considered a true *stress guru* — she also serves as an **advisor to Oura Health**.

Most wearables rely on **indirect estimates** based on heart rate, HRV, and similar metrics. To truly understand stress, we’d need to monitor **adrenaline** and **cortisol** levels directly. But interestingly, even **consumer-grade devices** capable of that are starting to appear on the market: [Cortisol Tests, 1-monthThis package includes:4 tests/monthsUnlimited access to Eli app![](https://www.fitnesator.cz/content/images/icon/favicon_icon_44d4e266-5bc3-4e74-a3da-bf61e86787d7_32x32.png)Eli Health![](https://www.fitnesator.cz/content/images/thumbnail/Group1538231827.png)](https://eli.health/products/cortisol?ref=lordofthesmartrings.com) ## 👂 **BONUS – Limitless Pendant** I’m still exploring possible **use cases** for the **Limitless Pendant** — a wearable pendant that listens to *everything* around you and then lets an **LLM model** creatively (and sometimes questionably) interpret what it heard. :) And as luck would have it, the pendant happened to be **active during my interview**. So, after it was all over, I asked the model… ![](https://storage.ghost.io/c/01/ca/01ca9f1d-13b0-43d5-a8fe-dac2f7d3dc2f/content/images/2025/11/image-1.png) And the **LLM** replied: ![](https://storage.ghost.io/c/01/ca/01ca9f1d-13b0-43d5-a8fe-dac2f7d3dc2f/content/images/2025/11/image-2-1.png) When it comes to **stress**, though, LLMs aren’t exactly great at detecting tone, voice tremor, irony, or subtle emotional cues. So the Limitless response was more of a **generic (and typically flattering)** one — after all, the AI probably doesn’t want to upset me… I might delete it. 😄 [Limitless Pendant](https://fitnesator.link/pendant?ref=lordofthesmartrings.com) VIDEO-VERSION
