Question 14

Describe a time you had to work with incomplete or messy data. How did you handle it?
Answer:
In a previous project, we had sensor data with a lot of missing values. I used imputation techniques to fill in the missing data based on statistical analysis of the available data. I also performed sensitivity analysis to assess the impact of the imputed values on the results.

Question 15

What is your experience with integrating data from different manufacturing systems (e.g., ERP, MES, SCADA)?
Answer:
I have experience with integrating data from various manufacturing systems, including ERP, MES, and SCADA. I use APIs, data connectors, and ETL tools to extract, transform, and load data from these systems into a central data warehouse. This allows for a holistic view of the manufacturing process.

Question 16

What is your approach to identifying root causes of manufacturing defects using data analytics?
Answer:
I use a combination of statistical analysis, process knowledge, and domain expertise to identify root causes of manufacturing defects.
