10+ Freo Interview Questions and Answers

Both development and testing are equally important for delivering quality software.

• Development and testing are two sides of the same coin.

• Development creates the software while testing ensures its quality.

• Testing helps identify and fix bugs, improving the overall quality of the software.

• Without testing, software can have critical bugs that can lead to disastrous consequences.

• Both development and testing require different skill sets and are equally important for delivering qua...read more

Relocation to Pune is fine if the candidate is open to moving for the job.

• Consider the candidate's willingness to relocate

• Evaluate the benefits of working in Pune

• Discuss any potential challenges or concerns with relocation

OOPS Concepts are the principles of Object-Oriented Programming that help in designing and implementing software systems.

• Abstraction: Hiding the implementation details and showing only the necessary information.

• Encapsulation: Binding data and functions together to protect data from outside interference.

• Inheritance: Creating new classes from existing ones, inheriting properties and methods.

• Polymorphism: Ability of objects to take on multiple forms or behaviors.

• Example: A car i...read more

C code can be generated in MATLAB using the MATLAB Coder app or by using the 'codegen' function.

• MATLAB Coder app allows users to generate C code from MATLAB code

• The 'codegen' function can be used to generate C code programmatically

• Generated C code can be optimized for specific hardware platforms

• C code can be integrated with other programming languages or software tools

• Example: codegen myFunction -args {arg1,arg2} -config:lib -report

Model in Loop is a simulation technique where a physical system is connected to a computer model for testing and validation.

• Model in Loop (MiL) is a part of the V-Model of software development.

• It involves connecting a physical system to a computer model to test and validate the model.

• MiL is used in various industries such as automotive, aerospace, and defense.

• It helps in identifying and fixing errors in the model before implementing it in the physical system.

• Examples of MiL i...read more

Python has several built-in datatypes including numeric, sequence, and mapping types.

• Numeric types include integers, floats, and complex numbers.

• Sequence types include lists, tuples, and strings.

• Mapping types include dictionaries.

• Python also has boolean and None datatypes.

• Datatypes can be converted using built-in functions like int(), str(), and float().

Software in Loop (SIL) is a testing technique where software is tested in a simulated environment.

• SIL is used to test software components before integrating them into a larger system.

• It involves creating a simulated environment that mimics the real-world environment in which the software will operate.

• SIL can help identify and fix software defects early in the development process.

• Examples of SIL tools include Simulink, LabVIEW, and dSPACE.

• SIL is often used in the automotive an...read more

A database is a collection of data that is organized in a way that allows for efficient retrieval and manipulation.

• A database can be relational or non-relational

• Examples of databases include MySQL, Oracle, MongoDB

• Data is stored in tables or documents

• Queries can be used to retrieve specific data

Structures and unions are used in C to define custom data types that can hold multiple variables of different data types.

• Structures allow grouping variables of different data types under a single name.

• Unions are similar to structures but they share the same memory location for all its members.

• Structures are used to represent complex data structures like linked lists, trees, etc.

• Unions are used when only one of the members needs to be accessed at a time.

• Example of a structure:...read more

EU-MDR stands for European Union Medical Device Regulation.

• EU-MDR is a set of regulations that govern the safety and performance of medical devices in the European Union.

• It replaces the previous Medical Device Directive (MDD) and Active Implantable Medical Device Directive (AIMDD).

• EU-MDR aims to enhance patient safety, improve transparency, and strengthen the regulatory framework for medical devices.

• It introduces new requirements for clinical evidence, post-market surveillanc...read more

My area of interest is computer programming and software development.

• I enjoy learning new programming languages and frameworks.

• I have experience in developing web applications using HTML, CSS, JavaScript, and React.

• I am also interested in mobile app development using Java and Kotlin for Android and Swift for iOS.

• I am always looking for opportunities to improve my skills and contribute to open-source projects.

A linked list is a data structure where each element points to the next element in the sequence.

• Consists of nodes where each node contains data and a reference to the next node

• Can easily insert or delete elements without shifting other elements

• Types include singly linked list, doubly linked list, and circular linked list

Code to check if a given string is a palindrome

• Iterate through the string from both ends and compare characters

• Use built-in functions like reverse() to simplify the code

• Consider ignoring spaces and punctuation for a more accurate check

OOPs concept stands for Object-Oriented Programming, which is a programming paradigm based on the concept of objects.

• OOPs focuses on creating objects that contain data and methods to manipulate that data

• It involves concepts like inheritance, encapsulation, polymorphism, and abstraction

• Example: Inheritance allows a class to inherit properties and methods from another class

2's complement of a number is a mathematical operation that involves flipping the bits of a binary number and adding 1 to the result.

• To find the 2's complement of a binary number, invert all the bits and add 1 to the result.

• For example, the 2's complement of 0101 is 1011.

• 2's complement is commonly used in computer arithmetic to represent negative numbers.
