Trajectory Interview Questions and Answers
Ques:- What is the difference between front-end and back-end development
Right Answer:
Front-end development involves creating the visual and interactive aspects of a website or application that users see and interact with, using technologies like HTML, CSS, and JavaScript. Back-end development focuses on the server-side, handling the database, server logic, and application functionality that users do not see, typically using languages like Python, Java, or Ruby, along with databases like MySQL or MongoDB.
Ques:- What is software refactoring and why is it important
Right Answer:
Software refactoring is the process of restructuring existing computer code without changing its external behavior. It is important because it improves code readability, reduces complexity, enhances maintainability, and helps eliminate technical debt, making future development easier and more efficient.
Ques:- What is the role of CMSIS in ARM development
Right Answer:
CMSIS (Cortex Microcontroller Software Interface Standard) provides a standardized software framework for ARM Cortex-M microcontrollers, facilitating easier development by offering a set of APIs, device drivers, and middleware that streamline the programming process and enhance code portability across different ARM devices.
Ques:- What are internal tables in ABAP and how are they used
Right Answer:
Internal tables in ABAP are data structures that hold multiple rows of data in memory, similar to arrays in other programming languages. They are used to store, manipulate, and process sets of data dynamically during program execution. Internal tables can be used for operations like reading, inserting, updating, and deleting data, and they can be defined with various types of keys and structures.
Ques:- How do you migrate content into Alfresco from legacy systems
Right Answer:
Use the Alfresco Bulk Import Tool, custom scripts leveraging the Alfresco API, or dedicated migration tools depending on the complexity and volume of content.
Ques:- What is an API and how does it work
Right Answer:
An API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate with each other. It defines the methods and data formats that applications can use to request and exchange information. APIs work by sending requests from one application to another, which then processes the request and sends back a response.
Ques:- What is API testing and what tools can be used for it
Right Answer:
API testing is the process of verifying that an application programming interface (API) functions as expected, ensuring it meets the requirements for functionality, reliability, performance, and security. Tools that can be used for API testing include Postman, SoapUI, JMeter, RestAssured, and Swagger.
Ques:- What is the difference between synchronous and asynchronous API calls
Right Answer:
Synchronous API calls wait for the response before moving on to the next task, while asynchronous API calls allow the program to continue executing other tasks while waiting for the response.
Ques:- What is rate limiting in APIs and how is it implemented
Right Answer:
Rate limiting in APIs is a technique used to control the number of requests a user can make to an API within a specific time period. It is implemented by setting thresholds (e.g., requests per minute) and using mechanisms like tokens, counters, or IP address tracking to monitor and restrict access when the limit is exceeded.
Ques:- What are RESTful principles and how do they apply to API design
Right Answer:
RESTful principles include:

1. **Statelessness**: Each API call must contain all the information needed to understand and process the request, with no stored context on the server.
2. **Client-Server Architecture**: The client and server are separate, allowing for independent development and scalability.
3. **Uniform Interface**: A consistent way to interact with resources, typically using standard HTTP methods (GET, POST, PUT, DELETE).
4. **Resource-Based**: APIs should expose resources (data entities) through URIs, and clients interact with these resources.
5. **Representation**: Resources can be represented in various formats (like JSON or XML), and clients can request the format they prefer.
6. **Cacheability**: Responses should indicate whether they can be cached to improve performance and reduce server load.

These principles guide the design of APIs to be scalable, efficient, and easy to use.
Ques:- What is a pivot table and how do you use it in Excel or other tools
Right Answer:
A pivot table is a data processing tool that summarizes and analyzes data in a spreadsheet, like Excel. You use it by selecting your data range, then inserting a pivot table, and dragging fields into rows, columns, values, and filters to organize and summarize the data as needed.
Ques:- What are descriptive and inferential statistics
Right Answer:
Descriptive statistics summarize and describe the main features of a dataset, using measures like mean, median, mode, and standard deviation. Inferential statistics use sample data to make predictions or inferences about a larger population, often employing techniques like hypothesis testing and confidence intervals.
Ques:- What is regression analysis and when is it used
Right Answer:
Regression analysis is a statistical method used to examine the relationship between one dependent variable and one or more independent variables. It is used to predict outcomes, identify trends, and understand the strength of relationships in data.
Ques:- What are the different types of data distributions
Right Answer:
The different types of data distributions include:

1. Normal Distribution
2. Binomial Distribution
3. Poisson Distribution
4. Uniform Distribution
5. Exponential Distribution
6. Log-Normal Distribution
7. Geometric Distribution
8. Beta Distribution
9. Chi-Squared Distribution
10. Student's t-Distribution
Ques:- What is a hypothesis and how do you test it
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.
Ques:- What specific training have you had that would be relevant to this project manager job?
Right Answer:
I have completed a Project Management Professional (PMP) certification, attended workshops on Agile methodologies, and participated in training on risk management and stakeholder communication. Additionally, I have experience using project management software like Microsoft Project and Trello.
Ques:- How did diagonal of location.
Right Answer:
The diagonal of a location refers to the shortest distance between two opposite corners of a rectangular area, calculated using the Pythagorean theorem: ( text{Diagonal} = sqrt{(text{Length}^2 + text{Width}^2)} ).
Ques:- What is Change and configuration management repositoty
Right Answer:
A Change and Configuration Management Repository is a centralized database that stores information about changes made to a project, including configuration items, version control, and documentation. It helps track modifications, manage versions, and ensure that all team members have access to the latest project information.
Ques:- What do you mean by time & material contracts?
Right Answer:
Time and material contracts are agreements where a client pays for the actual time spent by the contractor's employees and the materials used in the project, rather than a fixed price.
