40 Jedox Interview Questions and Answers | HR, Technical & Aptitude Prep

Ques:- What are the differences between Agile, Waterfall, and DevOps methodologies

Asked In :- Adapty Solutions, GreyOrange, POPCORNAPPS SOFTWARE PVT, Yudiz Solutions, Apttus Software, TechRyde, AgilePoint Software India, NICE inContact, Winshuttle Software (India), Bombay Softwares,

Right Answer:
Agile is an iterative approach that focuses on collaboration and flexibility, allowing for changes throughout the development process. Waterfall is a linear and sequential model where each phase must be completed before moving to the next, making it less adaptable to changes. DevOps is a culture and set of practices that combines software development (Dev) and IT operations (Ops) to improve collaboration, automate processes, and shorten the development lifecycle, emphasizing continuous integration and delivery.

Aem Developer

Ques:- Can you explain the architecture of AEM and its core components (Sling, OSGi, JCR)

Asked In :- DREAMORBIT SOFTECH PVT, Novalnet e-Solutions, Bhanguz, Antier Solutions, Target Integration, Shipmnts, CodeCraft Technologies, MAK Controls & Systems, VSPLASH TECHLABS, Corent Technology,

Right Answer:
AEM (Adobe Experience Manager) architecture is based on three core components:

1. **Sling**: A web framework that maps HTTP requests to content resources. It allows developers to create dynamic web applications by using a resource-oriented approach, enabling easy access to content stored in the JCR.

2. **OSGi**: A modular system and service platform that allows for the dynamic loading and unloading of components (bundles). In AEM, OSGi manages the lifecycle of these components, enabling modular development and deployment.

3. **JCR (Java Content Repository)**: A specification for a content repository that stores and manages content in a hierarchical structure. AEM uses JCR to store all content, including pages, assets, and configurations, allowing for efficient content retrieval and management.

Together, these components enable AEM to deliver a flexible, scalable, and efficient content management solution.

ARM Compiler

Ques:- What are the main compiler optimization levels and what do they do

Asked In :- XIPHIAS Software Technologies, Finoit Technologies, Unica Solutions, SpotOn Software, sciative, Barracuda Networks, Infinite Computer Solutions India, Xobin, Ribbon Communications Inc, ISG NovaSoft Technologies,

Right Answer:
The main compiler optimization levels are:

1. **O0**: No optimization; the compiler generates the simplest code for debugging.
2. **O1**: Basic optimizations that improve performance without significantly increasing compilation time.
3. **O2**: More aggressive optimizations that enhance performance while still keeping compilation time reasonable.
4. **O3**: Maximum optimizations that may increase compilation time and can include aggressive techniques like loop unrolling.
5. **Os**: Optimizations focused on reducing code size.
6. **Ofast**: Disregards strict standards compliance for maximum performance, enabling all optimizations including those that may not be safe.

Each level balances between compilation time, execution speed, and code size.

AUTOSAR RTE Development

Ques:- How is error handling managed within RTE

Asked In :- RAKUTEN INDIA ENTERPRISE PVT, CodeClouds IT Solutions, Infostretch solutions, Microlise Telematics, Sequretek IT Solutions, AVIN Systems, Logisoft, DMZ, SRF, TMR,

Right Answer:
Error handling in the RTE (Runtime Environment) is managed through the use of error detection mechanisms, such as error hooks and status codes. The RTE provides interfaces for reporting errors, which can be handled by the application software components or the underlying operating system. Additionally, the RTE can log errors and trigger appropriate responses based on the severity of the error, ensuring that the system can recover or safely shut down if necessary.

ARM Compiler

Ques:- How are memory regions defined and managed in ARM compilation

Asked In :- FIS Global Business Solutions India, CakeSoft Technologies, Adnate IT Solutions, Happiest Minds Technologies Pvt., Third Eye Technologies, InfoObjects, ANSYS Software, Hexaview Technologies private, Ecom Express, Kalki Communication Technologies,

Right Answer:
Memory regions in ARM compilation are defined and managed using linker scripts or scatter files. These files specify the layout of memory, including the start and end addresses of different sections (like code, data, and stack) and how they should be placed in the available memory. The ARM compiler and linker use this information to organize the program's memory allocation during the build process.

Data Analytics

Ques:- What is a hypothesis and how do you test it

Asked In :- Vinove Software & Services Pvt Ltd, Medvarsity Online, Trigent Software, RANDSTAD INDIA PVT, Spadeworx Software Services, Dhruvsoft Services, TNQ Technologies, Clear Trail Technologies, Cloud Kinetics Technology Solutions, Startup - Navya Network,

Right Answer:
A hypothesis is a specific, testable prediction about the relationship between two or more variables. To test a hypothesis, you can use the following steps:

1. **Formulate the Hypothesis**: Clearly define the null hypothesis (no effect or relationship) and the alternative hypothesis (there is an effect or relationship).
2. **Collect Data**: Gather relevant data through experiments, surveys, or observational studies.
3. **Analyze Data**: Use statistical methods to analyze the data and determine if there is enough evidence to reject the null hypothesis.
4. **Draw Conclusions**: Based on the analysis, conclude whether the hypothesis is supported or not, and report the findings.

Data Analytics

Ques:- What is data normalization and why is it important

Asked In :- KRIOS Info Solutions, WSNE Consulting, MattsenKumar Services, Shipco IT, Itobuz Technologies, Fortunesoft IT Innovations, Spadeworx Software Services, Namecheap Web Services, TNQ Technologies, Define Labs,

Right Answer:
Data normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. It involves structuring the data into tables and defining relationships between them. Normalization is important because it helps eliminate duplicate data, ensures data consistency, and makes it easier to maintain and update the database.

Errors detected during execution of program are called exceptions. Exceptions can be handled using the try..except statement. We basically put our usual statements within the try-block and put all our error handlers in the except-block.
tryâ€¦except demo code:
>>> while True:
try:
x = int(raw_input("Enter no. of your choice: "))
break
except ValueError:
print "Oops! Not a valid number. Attempt again"
Enter no. of your choice: 12ww
Oops! Not a valid number. Attempt again
Enter no. of your choice: hi there
Oops! Not a valid number. Attempt again
Enter no. of your choice: 22
>>>

Global Variables are variables that are declared outside of a function, or in the ‘global space’. Any function within the program can access these variables.

Local Variables are variables that are declared within a function and is present within the local space of the function. Local variables cannot be accessed outside the function’s space.
