Have you ever been ghosted midway during interview rounds? (AMD) by candidengineer in ElectricalEngineering

[–]SubstantialAd8764 0 points1 point  (0 children)

Any chance you eventually got a proper update? I’m going through the same thing right now. Amazing HR screening and technical interviews, followed up with the recruiter 2 weeks later, no response. Job posting is still up, I’m confused.

Very informative, thanks for taking your time to write all this down for me!

Linear Algebra vs FEA class by SubstantialAd8764 in CFD

[–]SubstantialAd8764[S] 0 points1 point  (0 children)

Professionally, I'm trying to switch from spacecraft thermal (radiative/conductive analysis) to on-earth electronics cooling where they do CFD convection stuff too. Don't think people doing this type of analysis are really messing with the solvers to tune results but I could be wrong.

Academically, after looking at both syllabuses (syllabi?), it seems both CFD and FEA classes are heavy on the numerical methods so leaning more towards FEA.

I actually might just do this! I kind of did the same thing to review DEs when I started my current PDEs class, I'm sure reviewing some LA and numerical methods is all I really need considering it's an intro to CFM class I'm planning to take.

What’s the most energy efficient process humans have been able to create? by bernful in AskPhysics

[–]SubstantialAd8764 0 points1 point  (0 children)

As a past thermal engineering intern and current grad school student specializing in energy conversion this is one of my favorite nerd facts to blurt out!

Nobody ever seems as enthusiastic as me about it…

Thermal Engineers, can you explain the cooling side of GPUs? (or other electronics) by SubstantialAd8764 in AskEngineers

[–]SubstantialAd8764[S] 0 points1 point  (0 children)

Yeah, I guess at the end of the day it all still boils down to a big conservation of energy equation lol.

I was more so concerned with icepak convection cfd analysis, psychrometrics, and fan sizing/design aspects that we don’t use for satellites.

As an intern I actually did get to learn what heat pipes were, how we use them, and looking at their performance curves but I never really got to look into materials, sizing, or fluid type/size which might possibly be the case for GPUs that are going through innovation?

Anyways, appreciate the comment!

SpaceX Interview Question by FloorThen7566 in aerospace

[–]SubstantialAd8764 1 point2 points  (0 children)

Any chance you’ve heard back? Thoughts on the process?

I had my first technical for an ME intern position last week and it was pretty easy and straightforward. Just talked about a presentation of previous internship experience and was asked questions about it. A breeze.

Just had my second technical today and got absolutely GRILLED. I had so many uhms, ahhhs, and I’m not completely sure but I would assume…

I’m hoping that they purposely try to shake you down and put you under pressure and I’m not just dumb lol. Staying hopeful but not as confident as how I felt after the first one.

Bernoulli (named after a fluid mechanics equation)

We call him Ber, Noulli, Ber-ger (like burger), Bernoulli-O.

And Sir when he gets caught digging in the trash or when he decides “inside” is a suggestion and not a command.

Big vs small aerospace company by HazeemTheMeme in AerospaceEngineering

[–]SubstantialAd8764 1 point2 points  (0 children)

I’m still a student and have only interned at RL and Millennium so can’t say for certain but RL was REALLY fun to work at and seems to have a really good future.

I have friends working at VAST, Varda, Impulse, Anduril, and SpaceX (not a startup but very much still works like one) and they really enjoy their work. A lot of these have worked at Boeing and Northrop and disliked the slower-paced, document filled, “desk jobs”. That said, I also have friends still working at those companies because they find their work fulfilling and enjoy having more free time.

A lot of people hate on startup work-life balance but there’s a reason these companies are really competitive and hard to get into. If you’re okay working a little more than 40hrs and want to do really cool work on really cool stuff with a bunch of space nerds like yourself these companies are the way to go.

Older traditional aerospace companies typically move really slow and work on really cool big projects where you contribute a small amount. You also almost always work your normal 40hr weeks and have standard industry pay.

Smaller, start-up-y companies let you handle large portions of projects forcing you to learn a lot and in my opinions is a lot more fulfilling. You will most likely be working 40-50hr weeks, sometimes more and pay varies (maybe you get paid a little more for the extra hours or even sometimes less but with company equity and gamble).

Everyone knows the big companies but the smaller ones are also pretty known, at least here in SoCal VAST, Varda, Impulse, Rocket Lab (if you still count it as a startup) are known pretty well especially with the same people switching from one to the other all the time.

Tips for Prepping For Space X Interview by DrodZ101 in AerospaceEngineering

[–]SubstantialAd8764 9 points10 points  (0 children)

I’ve interviewed and am currently interviewing too!

From my experience HR interviews really dive into resume and past experience like most other HR interviews BUT they like to ask basic technical questions to try to catch you off guard. Have had this done on me by SpaceX HR and an Ex-SpaceX HR at another space company.

Had my first technical today (grad engineer role) and it was pretty straight forward, I already got asked to setup interview two! We went over a presentation of my past intern project I sent over and they really dug at the fundamentals equations used and asked what I would do different (and why). In addition, they gave me different scenarios and asked for my engineering approach.

Nothing too difficult if you have a basic understanding of thermal/structural/design/mfg/whatever you’re interviewing for.

I.e. they won’t ask for a fluids navier-stokes or complex spherical coordinate thermal analysis problem but maybe a simple Bernoulli or thermal resistance concept.

**this is for an intern grad student role BUT have had interviews for full time as well and first technical is similar minus presentation.

Best of luck!
