The keys should be unique among the sibling lists. But we can use the same keys if we have two different arrays.

After Effects

Ques:- Can you describe the difference between After Effects and Premiere Pro

Asked In :- Tekno Point Multimedia, coreel technologies, rock paper scissors,

Right Answer:
After Effects is for creating motion graphics, visual effects, and compositing. Premiere Pro is for video editing and assembling footage. After Effects excels at creating elements from scratch, while Premiere Pro excels at organizing and cutting existing video and audio.

After Effects

Ques:- What’s the difference between position, scale, rotation, and opacity keyframes

Asked In :- Tekno Point Multimedia, coreel technologies, psiog digital, 3d artist / senior 3d generalist,

Right Answer:
* **Position:** Changes an object's location in the composition.
* **Scale:** Alters the size of an object.
* **Rotation:** Spins an object around its anchor point.
* **Opacity:** Adjusts an object's transparency.

After Effects

Ques:- How do you use keyframes for animation in After Effects

Asked In :- coreel technologies, yd, rock paper scissors,

Right Answer:
In After Effects, you use keyframes by first selecting a property you want to animate (like Position, Scale, Rotation, or Opacity). Then, you set initial values for that property at a specific time, creating the first keyframe. Move the timeline indicator to a different time, change the property's value, and After Effects automatically creates a new keyframe. After Effects then interpolates the values between those keyframes to create the animation.

After Effects

Ques:- What plugins or third-party tools have you used to enhance After Effects projects

Asked In :- Pixelvide, coreel technologies,

Right Answer:
I've used plugins like Red Giant Complete Suite (particular mentioning Trapcode Particular, Magic Bullet Suite), Boris FX Sapphire, Video Copilot's Element 3D and Optical Flares, and plugins from aescripts + aeplugins, depending on project needs.

2. Layout Grids

Mobile: Simpler grid (e.g., 4–column).
Desktop: More complex grids (e.g., 12–column) for flexible layouts.

3. Constraints

Set constraints for responsive behavior (e.g., text stays pinned to the left or center resizes with screen).

4. Component Responsiveness

Design components to adapt for both screen sizes using Auto Layout and Resizing properties.

5. Breakpoints

Create separate frames for each breakpoint (e.g., mobile, tablet, desktop) to visualize responsiveness.

Figma

Ques:- What are Boolean operations in Figma? Can you give an example?

Asked In :- Velocity Software Solutions, Aliens Group, Wonderbiz Technologies, EvolveWare, Zysk Technologies, coreel technologies, adam milo, maple, flm, ola,

Right Answer:

Boolean operations in Figma are tools that combine shapes in different ways to create complex vector graphics. The four main types are:

Union – Combines all selected shapes into one.
Subtract – Removes the top shape from the bottom one.
Intersect – Keeps only the overlapping area.
Exclude – Removes the overlapping area and keeps the non-overlapping parts.

Software Development

Ques:- What are RESTful APIs and how do you implement them in software projects

Asked In :- Clear Trail Technologies, SWYM, toobler technologies, Godrej Infotech limited, STG Infotech INDIA LLP, Highbar Technocrat, ARMIA SYSTEMS, TechnoCipher IT Solutions, ITBP, Knowledge Splice,

Right Answer:
RESTful APIs are web services that follow the principles of Representational State Transfer (REST). They use standard HTTP methods (GET, POST, PUT, DELETE) to perform operations on resources identified by URLs. To implement RESTful APIs in software projects, you typically:

1. Define the resources and their representations (e.g., JSON or XML).
2. Use HTTP methods to create, read, update, and delete these resources.
3. Set up routing in your server to handle requests and responses.
4. Ensure stateless communication, meaning each request from a client contains all the information needed to process it.
5. Optionally, implement authentication and authorization for secure access.

AUTOSAR RTE Development

Ques:- How does RTE manage inter-ECU communication

Asked In :- Muvi Entertainment, Happiest Minds Technologies Pvt., TVISHA TECHNOLOGIES PVT, Promact Infotech, Emtec Technologies, Xobin, Proseon Technologies, Newdream Data Systems, CloudMoyo, Inc, AVIN Systems,

Right Answer:
The RTE (Runtime Environment) manages inter-ECU communication by using a standardized communication mechanism that allows different ECUs (Electronic Control Units) to exchange data through defined interfaces. It utilizes the COM (Communication) module to handle message transmission and reception, ensuring that data is sent and received according to the AUTOSAR specifications, including support for different communication protocols like CAN, LIN, and Ethernet.

AUTOSAR

Ques:- How are AUTOSAR configurations handled using tools like DaVinci or EB tresos

Asked In :- Xoriant Solutions Pvt Ltd, Shipco IT, Ziffity Solutions, Namecheap Web Services, Spectra Medix India, Principal Global Services, OPENSPACE SERVICES, Emtec Technologies, Microlise Telematics, Hinduja Tech,

Right Answer:
AUTOSAR configurations are handled using tools like DaVinci or EB tresos by providing a graphical interface to define and manage software components, their parameters, and communication settings. These tools allow users to create, modify, and validate the AUTOSAR XML files (ARXML) that describe the system architecture, ensuring compliance with AUTOSAR standards and facilitating integration into the overall software development process.

Aem Developer

Ques:- Can you explain how content is stored and retrieved in AEM’s JCR repository

Asked In :- Chegg India, Recodem, SpotOn Software, Amtech Electronics India, Unicommerce eSolutions, Innodata, Code Genesis, Cohere, Gem Software Solutions, CSG Systems,

Right Answer:
In AEM, content is stored in the Java Content Repository (JCR) using a hierarchical structure of nodes and properties. Each piece of content is represented as a node, which can have child nodes and properties that store data. To retrieve content, AEM uses the JCR API, allowing developers to query the repository using SQL2 or XPath queries, or by navigating the node structure programmatically.
