Hello Mr. Goovaerts,
 +
 +
My name is Ted Havelka.  I am a friend and fellow alum of Andrew Greenberg, and one of the many Portland Aerospace Society participants who played a role, if small, over the years.  I still keep in touch with Andrew.  I am also employed as a firmware engineer at a local, Clackamas Oregon company where we have recently posted a job opportunity that's ideally suited for recent graduates on an embedded systems and firmware track.  Andrew suggested that I reach out to you and pass along our job posting.  Here is the link:
 +
 +
*  https://recruiting.ultipro.com/ROP1001ROPER/JobBoard/5635cac7-6c69-44a7-850c-cf35112ce343/OpportunityDetail?opportunityId=eea2677d-12ab-4420-8507-0bded05f2e0f
 +
 +
My supervisor is spearheading the initial interviews and will make hiring decisions.  As the lead firmware developer on a small IIoT team I'll be involved in interviewing candidates who we call for a second more in depth interview.  I hope it is appropriate for me to reach out to you this way.  Let me know whether there will be any graduates this spring of 2022 with a focus on firmware and embedded level design.
 +
 +
Thank you,
 +
 +
- Ted

Ted's questions:
 +
 +
(1)  In your skills and work history you've done a ton of stuff, when do you sleep?
 +
 +
(2)  Why the (potentially more challenging) switch from molecular biology to electrical engineering?
 +
 +
(3)  Can you describe the "skills development process" you mention leading at Atypical Technology and Advanced Projects (ATAP)?
 +
    ( Is ATAP part of or the more modern times Computer Action Team at PSU School of Engineering? )
 +
 +
 +
 +
(4)  Given your wide range of technical skills what most caught your eye in our Firmware Developer job description?

Questions for Mr. Bliss Brass
 +
 +
( Quick overview . . . )
 +
Your program of engineering study was specifically Computer Engineering, CE rather than EE by formal designation?  What made you choose this path?
 +
 +
 +
 +
Specific project questions . . .
 +
 +
Work at MSX:
 +
 +
  (1)  Can you talk a bit about your role in the medical wrist device firmware project at MSX?
 +
 +
  (2)  Can you describe the tools and work steps, generically ok, in your CNC machine firmware debugging?
 +
 +
 +
 +
Summer Project question:
 +
 +
  (3)  Does the algorithmic project assignment work involve primarily or solely software design and testing?  Or any hardware?
 +
 +
  (4)  Looks like there's a lot of documentation in your summer project.  Do you like to document your own personal projects, such as things you may share on github or just have time to pursue on weekends?
 +
 +
  (5)  In a sentence or two how would you briefly summarize what each of "requirements", "specifications" and "test plan" mean?
 +

Some important skills for Jared:

  Moter controller,
 +
  SPI (bit banged),
 +
  dual ARM Cortex-M0+ controllers
 +
  FreeRTOS
 +
  C and assembly
 +
 +
 +
(1)  Can you describe a little bit about what started your interest in embedded design and problem solving?
 +
 +
(2)  Briefly, what is your experience working with FreeRTOS?  ( Example:  what features of FreeRTOS have you used, how does your code integrate with it? )
 +
 +
(3)  Is the SPI motor project one you got to choose, or one of a selection of capstone or senior eng' projects?
 +
 +
(4)  What are the greatest values you see to complete and well organized project documentation?
 +
 +
(5)  What does your collaborative git experience look like?  ( Example:  how often creating or answering pull requests, how many active developers working in same repo with you? )
