Intel Interview Questions and Answers

Metrics like cosine similarity measure the similarity between two vectors in various contexts, often used in text analysis and machine learning.

• Euclidean Distance: Measures the straight-line distance between two points in Euclidean space. Example: Distance between two points in 2D.

• Jaccard Similarity: Measures similarity between finite sample sets. Example: Similarity between two sets of user preferences.

• Pearson Co...read more

The ARM Cortex-A series is a popular microarchitecture designed for high performance and energy efficiency in mobile devices.

• Designed for mobile and embedded systems, balancing performance and power consumption.

• Utilizes a pipeline architecture to improve instruction throughput.

• Supports advanced features like out-of-order execution and branch prediction.

• Examples include Cortex-A53 and Cortex-A72, widely used in sma...read more

Quick signoff checks ensure design integrity and compliance before finalizing physical layouts in semiconductor design.

• Design Rule Check (DRC): Ensures layout adheres to manufacturing rules, e.g., minimum spacing between metal layers.

• Layout Versus Schematic (LVS): Confirms that the physical layout matches the intended circuit design, e.g., checking transistor connections.

• Electrical Rule Check (ERC): Validates elec...read more

VLSI flow involves a series of steps to design integrated circuits from specifications to fabrication.

• Specification: Define the requirements and functionality of the circuit.

• Architecture Design: Create a high-level design, including block diagrams.

• Logic Design: Develop the circuit using logic gates and HDL (e.g., Verilog, VHDL).

• Synthesis: Convert HDL code into a gate-level netlist.

• Placement: Arrange the components...read more

Basic rework of a PCB involves repairing or modifying the board to ensure proper functionality and reliability.

• Identify the faulty components using testing equipment like multimeters.

• Desolder defective components using a soldering iron or desoldering pump.

• Replace with new components, ensuring correct orientation and placement.

• Resolder connections carefully to avoid shorts or cold joints.

• Test the PCB after rework t...read more

let, const, and var are JavaScript keywords for variable declaration with different scopes and mutability.

• var: Function-scoped or globally-scoped, can be redeclared and updated. Example: var x = 10; x = 20;

• let: Block-scoped, can be updated but not redeclared in the same scope. Example: let y = 10; y = 20; // valid

• const: Block-scoped, cannot be updated or redeclared. Must be initialized at declaration. Example: con...read more

Hoisting is a JavaScript mechanism where variable and function declarations are moved to the top of their containing scope during compilation.

• Variables declared with 'var' are hoisted, but their initialization is not. Example: console.log(a); var a = 5; // undefined

• Function declarations are fully hoisted, allowing them to be called before their definition. Example: greet(); function greet() { console.log('Hello');...read more

The graphics pipeline is a sequence of steps that transforms 3D models into 2D images on the screen.

• 1. Vertex Processing: Transforms 3D coordinates into 2D space (e.g., applying transformations like translation, rotation).

• 2. Clipping: Removes parts of objects outside the viewable area to optimize rendering.

• 3. Rasterization: Converts vector graphics into pixels, determining which pixels are affected by the shapes.

• 4...read more
