Interview
Interview has been done in two steps.
1st step done by HR with the standard questions in strict relation with work experience, current skills and objectives which I would identify by getting this role.
English was mentioned as one of the advantages on the opportunity so half of interview was done in English.
2nd step done together with direct manager for in depth skills. Several technical questions based on component samples and technical datasheet specifications.

Interview Experience at Plexus (Bayan Lepas, Riverside Site)
This was one of the most unpleasant interview sessions I’ve experienced:
The interviewer reviewed my payslip directly, which I believe should be handled by HR since it is private and confidential.
I was not given the opportunity to properly answer questions. Instead of open-ended questions that allow me to explain my experience, I was limited to only close-ended ones.
It felt like the decision not to proceed with me was already made before the interview, raising the question of why waste the candidate’s time in the first place.
The interviewer used inappropriate words and even told me I was wasting his time — very unprofessional behavior.
I cannot comment on the actual work environment at Plexus Bayan Lepas (Riverside site), but based on the interview alone, I walked away with a very negative impression of the company’s culture and professionalism.

Question 1
Some of the questions asked were inappropriate and irrelevant, such as:
“Why not ask your previous HR to transfer you to a Quality position instead of changing jobs?”
“Why did you take medical leave that month?”
These do not reflect a fair or professional interview process.
