I only did the first interview. It was a Zoom interview, so it was possible to do it remotely. It was very technical.

The Zoom call was arranged by email with the Managing Director. The interviewer was the Head of Engineering, despite the fact that more of the engineering staff was likely listening to the Zoom call.

More of the questions were very technical, focusing on how oscilloscopes work, their characteristics, and how to analyze signals.

One question asked what makes an oscilloscope "expensive," and what differentiates a good oscilloscope from a less powerful one.

Another asked how, in a digital oscilloscope, one would detect if a prototype signal is working properly or not, and what type of signal to introduce to detect that the output is correct.
