The interview process consisted of three main steps:

• The first step was a basic HR interview, which included some questions about my background and experience.
• The second step involved a basic interview with the department manager. He attempted to delve into technical details, but we ran out of time, and I couldn't provide in-depth answers.
• The third step was a technical interview with a staff manager from the US. I spoke about my background for five minutes, and the remaining twenty-five minutes were filled with technical questions related to my experience. I believe I answered all questions correctly, except for one.

After the last interview, I received an email informing me of my rejection.

My overall experience was fairly positive. All interviewers were very helpful, and the entire process was well-structured. They informed me about interview scheduling on a day-by-day basis.

Here's a summary of the key questions from the interview:

• Understanding behind SPC, how to calculate Cp, Cpk, Pp, Ppk, and where to apply each.
• Understanding behind OEE. What can be done to improve OEE of a production line.
• How to calculate takt time.

Regarding robots and PLCs, I was asked about my level of understanding. I mentioned my familiarity with robots and PLCs, and they probed further into my conceptual understanding.

I was asked about 8D and Lean tools, such as 5 WHY and Bonefish, and I explained each of these tools.

I was asked to provide an example of when and how I used a tool like 5 WHY. I gave an example, and the interviewer then asked how I evaluated the results.

I was asked about the types of PLCs and PLC software I have used. I stated that I worked with the S7-1200 PLC and Siemens TIA Portal, but my familiarity was limited to simple projects rather than in-depth knowledge.

They also asked about the processes my current company uses to produce parts, and I explained these processes one by one.

These were the most important questions I recall. All other questions pertained to my previous experiences.
