Goldman Sachs Interview Questions and Answers

Radiography testing (RT) and ultrasonic testing (UT) are both non-destructive testing methods used to detect flaws in materials.

• Radiography testing uses X-rays or gamma rays to create an image of the internal structure of an object, while ultrasonic testing uses high-frequency sound waves.

• RT is typically used for thicker materials and can detect both surface and subsurface defects, while UT is more commonly used for thinner materials and can only detect surface defects.

• RT pro...read more

Essential variables are crucial for the functioning of a system, while non-essential variables are not necessary but may provide additional information.

• Essential variables are required for the system to operate correctly.

• Non-essential variables are not necessary for the system's basic functionality.

• Essential variables are typically directly related to the core purpose of the system.

• Non-essential variables may provide supplementary data or enhance the system's performance.

• For ...read more

Yes, MRB (Manufacturing Record Book) is a document that contains detailed information about the manufacturing process.

• MRB is a comprehensive record of all activities related to manufacturing, including design, production, testing, and quality control.

• It serves as a reference for future production runs and helps ensure consistency and quality.

• MRB typically includes information such as engineering drawings, specifications, inspection reports, test results, and certifications.

• It...read more

No, RT cannot replace UT examination.

• RT (Radiographic Testing) and UT (Ultrasonic Testing) are two different non-destructive testing methods used in engineering.

• RT uses X-rays or gamma rays to inspect the internal structure of an object, while UT uses sound waves to detect flaws or measure thickness.

• Each method has its own advantages and limitations, and they are often used in combination to ensure comprehensive inspection.

• For example, RT is effective for detecting internal d...read more

WPS stands for Welding Procedure Specification and PQR stands for Procedure Qualification Record.

• WPS is a document that provides detailed instructions on how to perform a specific welding procedure.

• It includes information on welding parameters, materials, pre-weld and post-weld treatments, etc.

• PQR is a record that documents the actual results of a welding procedure qualification test.

• It includes details of the test, such as the welding process used, materials, test results, e...read more
