NeoSOFT Interview Questions, Process, and Tips

PEP 8 is the style guide for Python code, promoting readability and consistency in Python programming.

• Encourages using 4 spaces per indentation level instead of tabs.

• Recommends limiting lines to 79 characters for better readability.

• Suggests using blank lines to separate functions and classes.

• Promotes using descriptive variable names, e.g., 'user_age' instead of 'ua'.

• Advises on proper import ordering: standard libraries...read more

Multithreading allows concurrent execution of tasks in Python, enhancing performance and responsiveness in applications.

• Concurrency: Multiple threads run simultaneously, improving application responsiveness.

• Thread Creation: Use the 'threading' module to create threads. Example: 'threading.Thread(target=func).start()'.

• Synchronization: Use locks (e.g., 'threading.Lock') to prevent race conditions when accessing shared re...read more

Method overloading allows multiple methods with the same name but different parameters; overriding replaces a method in a subclass.

• Method Overloading: Same method name with different parameters in the same class.

• Example: def add(self, a: int, b: int) and def add(self, a: float, b: float).

• Method Overriding: Subclass provides a specific implementation of a method already defined in its superclass.

• Example: class Animal ha...read more

Lists are flexible and can hold mixed data types; arrays are fixed-type and more efficient for numerical data.

• Lists can contain elements of different data types: ['apple', 42, 3.14, True]

• Arrays are typically used for numerical data and require all elements to be of the same type: array('i', [1, 2, 3])

• Lists are part of Python's built-in data types, while arrays require importing the 'array' module or using libraries lik...read more

Pandas is a powerful Python library for data manipulation and analysis, providing data structures like DataFrames and Series.

• DataFrame: A 2-dimensional labeled data structure, similar to a spreadsheet. Example: df = pd.DataFrame({'A': [1, 2], 'B': [3, 4]})

• Series: A one-dimensional labeled array capable of holding any data type. Example: s = pd.Series([1, 2, 3])

• Data manipulation: Easily filter, group, and aggregate data...read more

Pods are the smallest deployable units in Kubernetes, consisting of one or more containers.

• Pods are used to run and manage containers in Kubernetes

• Each pod has its own unique IP address within the Kubernetes cluster

• Pods can contain multiple containers that share resources and are scheduled together

• Pods are ephemeral and can be easily created, destroyed, or replicated

• Pods can be managed and scaled using Kubernetes contr

Worker process in IIS is a separate process that handles requests for web applications.

• Worker process runs independently from the main IIS process

• It manages requests for web applications hosted on the server

• Each worker process is assigned to a specific application pool

• Worker processes can be recycled or restarted to maintain performance

• Example: w3wp.exe is the default worker process for IIS

Utilisation in IIS refers to the percentage of time that a worker process is busy serving requests.

• Utilisation is a measure of how efficiently the server is handling incoming requests.

• It is calculated by dividing the total time the worker process is busy by the total time elapsed.

• A high utilisation rate may indicate that the server is overloaded and needs optimization.

• Monitoring utilisation can help in identifying perf...read more

A wildcard certificate is a type of SSL/TLS certificate that can secure multiple subdomains with a single certificate.

• Wildcard certificates are identified by an asterisk (*) before the domain name, allowing it to secure any subdomain under that domain.

• For example, a wildcard certificate for *.example.com can secure subdomains like blog.example.com, shop.example.com, etc.

• Wildcard certificates are cost-effective and conv...read more

To ensure high availability and scalability during deploying an application, utilize load balancing, auto-scaling, fault tolerance, and monitoring.

• Implement load balancing to distribute traffic evenly across multiple servers.

• Utilize auto-scaling to automatically adjust the number of instances based on traffic demand.

• Design for fault tolerance by using redundant components and failover mechanisms.

• Monitor the application...read more
