First interview was with some one who really have no knowledge about plant or data center system I mean field of study I.e chemist working on construction of data centers.LoL
First phone interview call
1- How does a steam boiler work
2 what kind of water treatment used
3-How to optimize these systems
Completely related and unrelated questions taking into account I’m a mechanical engineer. No complains here. Nice interview.
Second phone interview after like 2.5 weeks, then the guy is sick then pushed another week. Things happen I understand.
Second Phone interview, this guy was on something for sure like 🙃. Be aware this is a plant engineer position in a data center:
1- How doe a GFCI outlet works
2- what a voltage leading current circuit called
3-How does a VFD works
4- if you take an amp reading on one leg of a 3 phase motor and if u combined all three wires together and clamped them what are those readings LoL who the F would combine 3 wires.
5-what’s the out put signal of PLC called
6-if u have a blown fuse what’s and u took a voltage readings across when u have power, what would that reading be.
7- what’s the control voltage out of flow meter to connect to a PLC
8- if u have a 480v 3 phase with neutral leg and u measured between what is that voltage and Why
9- can we have VSD on 120v motor
