DMI Quality Assurance Interview Questions and Answers

Game testing is the process of evaluating a game's functionality, performance, and user experience.

• Game testing involves identifying and reporting bugs and glitches

• It also includes testing game mechanics and balancing

• Game testers may also evaluate the game's story, characters, and overall design

• Examples of game testing include alpha and beta testing, as well as focus group testing

Modal analysis is a technique used to study the dynamic characteristics of a system by identifying its modes of vibration.

• Modal analysis is used to determine the natural frequencies, damping ratios, and mode shapes of a structure or component.

• It helps in understanding the behavior of a system under different loading conditions.

• Modal analysis is commonly used in engineering fields such as aerospace, civil, and mechanica...read more

DOF stands for Degrees of Freedom and refers to the number of independent variables in an element.

• 1D elements have 2 DOF, typically displacement in x and rotation about x

• 2D elements have 3 DOF, typically displacement in x and y, and rotation about z

• 3D elements have 6 DOF, typically displacement in x, y, and z, and rotation about x, y, and z

Mesh quality criteria are used to evaluate the accuracy and reliability of a mesh in numerical simulations.

• Mesh quality criteria assess the shape, size, and connectivity of mesh elements.

• Common criteria include aspect ratio, skewness, and orthogonality.

• Aspect ratio measures the elongation of elements, with lower values indicating better quality.

• Skewness measures the distortion of elements, with values close to zero ind...read more
