Leader Quality Assurance Interview Questions and Answers

WPS/PQR limitations vary based on thickness and position of the material being welded.

• WPS/PQR limitations are determined by the welding code being followed.

• Thickness limitations are based on the code and the welding process being used.

• Position limitations are also determined by the code and welding process.

• For example, in ASME Section IX, the thickness limitations for SMAW welding in the 1G position are different than in the 6G position.

• Welding procedures must be qualified th...read more

Sanity testing checks specific functionalities after changes, while smoke testing verifies basic functionality of the build.

• Sanity testing is a narrow and deep approach, focusing on specific functionalities after changes.

• Smoke testing is a broad and shallow approach, ensuring the basic functionality of the application.

• Example of sanity testing: After a bug fix, testing only the affected feature to ensure it works correctly.

• Example of smoke testing: After a new build, checking...read more

Interpreting gear quality involves analyzing various factors such as material, design, manufacturing process, and performance.

• Evaluate the material used for the gear, such as steel, aluminum, or composite materials.

• Assess the design of the gear for factors like tooth profile, pitch, and pressure angle.

• Examine the manufacturing process to ensure proper machining, heat treatment, and quality control measures were followed.

• Test the performance of the gear under load conditions t...read more

Debugging a blank screen involves identifying the root cause through systematic checks and testing various components.

• Check browser console for errors (e.g., JavaScript errors).

• Inspect network requests to ensure all resources are loading correctly.

• Verify server response status codes (e.g., 404, 500).

• Clear browser cache and cookies to rule out caching issues.
