Ventura Securities Interview Questions, Process, and Tips for Experienced

HTTP/1 is a plain text protocol, HTTP/2 is binary and multiplexed, and HTTP/3 uses QUIC protocol for faster connections.

• HTTP/1 is a plain text protocol with no support for multiplexing, resulting in slower performance.

• HTTP/2 is a binary protocol that allows for multiplexing, header compression, and server push, improving performance.

• HTTP/3 is based on the QUIC protocol, which uses UDP instead of TCP for faster connecti...read more

We monitor application performance through various tools and techniques to ensure optimal functionality.

• Utilize monitoring tools such as New Relic, Datadog, or AppDynamics

• Set up alerts for key performance metrics like response time, error rate, and throughput

• Regularly analyze performance data to identify bottlenecks and areas for improvement

Debugging a microservice based application involves identifying and resolving issues in individual services.

• Start by reproducing the issue and gathering relevant logs and error messages

• Use logging and monitoring tools to track the flow of data and identify bottlenecks

• Isolate the problematic microservice and test it independently

• Check for compatibility issues between microservices and their dependencies

• Use debugging too...read more

Encoding decoding is the process of converting information from one format to another.

• Encoding is the process of converting information into a specific format that can be easily transmitted or stored.

• Decoding is the process of converting encoded information back into its original format.

• Examples of encoding decoding include converting text into binary code, compressing and decompressing files, and encrypting and decryp...read more

A linked list is a linear data structure where each element is a separate object with a pointer to the next element.

• Consists of nodes that contain data and a pointer to the next node

• Can be singly linked or doubly linked

• Used in implementing stacks, queues, and hash tables

A program to implement queue

• Create a class for the queue

• Use an array or linked list to store the elements

• Implement methods for enqueue, dequeue, and peek

• Handle edge cases like empty queue or full queue

A program to solve Sudoku puzzles

• Use backtracking algorithm to solve the puzzle

• Check for valid moves at each step

• Implement a function to check if a number is valid in a given cell

RDBMS stores data in tables with predefined schema while document DBs store data in flexible, JSON-like documents.

• RDBMS uses SQL for querying while document DBs use their own query language or JSON queries

• RDBMS is better suited for structured data while document DBs are better for unstructured or semi-structured data

• Examples of RDBMS include MySQL, Oracle, and SQL Server while examples of document DBs include MongoDB a
