I applied online. I interviewed at Schweitzer Engineering Laboratories in June 2020
Interview
Interview in an order. First HR with some specific technical questions related to power systems basics. The next round is technical with the engineers and the team. The last round is the presentation about your project from which you will be asked questions.
Interview questions [1]
Question 1

2. Given V, I in rectangular form calculate S, P, Q
3. 1+a+a2=0 and symmetrical forms what is a, a2
4. Given Va, Vb, Vc calculate +ve, -ve and zero sequence voltages
5. I f= ... calculate zero sequence current and related questions
6. time constant of, RL, RC circuits
7. Secondary impedance of transmission line. given CTR, PTR, Zline. Calculate Zrelay
8. Resistance of transformer with respect to the primary when primary and secondary voltage is given
9. Given V L... calculate Vab or vice versa
10. Truth tables XOR etc
I applied online. The process took 2 months. I interviewed at Schweitzer Engineering Laboratories (Pullman, WA)
Interview
Behavioral (30 minutes), followed by 1 hour technical and in person (1 day) interview. The interview process was smooth and made comfortable by the hiring manager and the interview team.

I applied online. I interviewed at Schweitzer Engineering Laboratories (Pullman, WA) in Apr 2017
Interview
3 interviews,
1) HR asks prerecorded question.
2) Telephonic with hiring team.
3) On-site (video during pandemic).
Focus is on fundamentals of power system.
HR will explain benefits during third round.
Slow responce from HR.
