As a practicing EE / RF comms engineer, I will say that it is very obvious when you're working with someone who thinks that their EE coursework wasn't useful for the real world.
- someguydave 5y agoYeah I have run into plenty of EE's who don't understand how to model a simple filter, for instance.
- cushychicken 5y agoThe first interview question is always an RC filter. It's an easy leading indicator of who has their shit together.
- panda88888 5y agoRC filter is like fizzbuzz for EE.
- rasz 5y agoOne of those is a basic building block used in pretty much everything, the other is software bullshit.
- krapht 5y agoI feel attacked. I'm a DSP engineer and I haven't implemented an analog filter since I graduated. If we got into detail on RC filter gain and phase shift I'd fail. Do I have to give my EE degree back?
- eigenvector 5y agoNo, but you at least realize an analog filter is a thing that exists. You don't remember the specifics, but you could study them if you needed to.
- rasz 5y agoAs an EE you should know what goes in front of ADC to avoid aliasing.
- posterboy 5y agoor you buy a basic building block ADC and follow instructions.
- throwaway348422 5y agoI think it depends on what is meant by details. For a DSP engineer, if details are not knowing the difference between and RC made with ceramic or film cap, I’d give a pass there. If details are not solving continuous time equations in the form 1/s, that’s probably a fail.
- posterboy 5y agoDon't the software methods have very similar problems?
- randomchars 5y agoLooping through a list of items, and doing different operations based on their value is an extremely common occurrence, and you’d hard pressed to find a codebase that doesn’t use that pattern somewhere.
- jmchuster 5y agoWelp, this is why interview fizzbuzz exists, because some people think of it as "software bullshit" instead of the simplest possible program you can imagine that should come out as fast as you can type it.
- posterboy 5y agofizzbuzz is literally a filter, albeit digital, and it involces a circuit, well a loop in most realizations, too. It's probably at the same level of complexity, give or take.
- cushychicken 5y agoAnd, like fizzbuzz, lots of people fail it.
- someguydave 5y agoyep exactly, even with training and degrees and claims of competence

- eigenvector 5y agoAs a practicing EE (power systems), I agree. It often becomes clear when someone is unable to distinguish a practical limit (this equipment is not rated for X, our operating procedures prohibit doing X) from a physical one (X is not possible because of underlying physical principles).
- disabled 5y agoThis. There are so many real world, practical, and pragmatic uses for EE. This example, which is basically knowing that the hardware specifications cannot meet the claims that are being made about a product, in an accurate or reliable fashion, is one I use on an everyday basis. You don’t fall for marketing gimmicks. Another thing is you know the relative price (ballpark figure) of the technology, as in how much it costs to make something, often just by eyeballing the actual product or by looking at its specifications. Sometimes this translates to more abstract and somewhat unrelated fields such as medications (if you read the patents and study them).
