Tip

Tip 1 : Have more hands-on experience. Do not just read about the topic, do a bit of a POC to establish understanding.
Tip 2 : Have complete end to end understanding of the things mentioned in your resume, do not add stuff that you have not worked upon or have lack of clarity.
Tip 3 : Start with the first-principle, interviewer does not want to see how great you are at coding but how you handle a problem statement. Elaborate your steps and your thinking process clearly.
Tip 4: Have atleast one project that you have developed from scratch, this will help you with framing other problem statements.

Coding problem1

Early morning.
Online VC
First was a problem statement to build a service to consume huge set of data (.pdf files ~200GB) without any data loss.
Interviewer was great in helping me understand the question and gave me good amount of time to think and implement.

1. System Design Question

Design a service to consume a huge set of data without any packet loss. Have a resilient system in place to avoid data loss and retry if required.
Use SQL to create an audit table to check for lost packets

Problem approach

Tip 1: Think from first principle, what is required to build a system like this?
Tip 2: Keep open communication with your interviewer to let them know what is your thought process.
Tip 3: Tell them areas where you are stuck and need some advice.

Asked about my interview rounds and how I think I performed.
Told about the culture of the team and how I can add to the same.

1. Basic HR questions

1. Expected CTC
2. Any other offers that I have.
3. Basic stuff about what I am expecting from CRED.

Problem approach

Tip 1: Be cool, you have made it so now it's all about the CTC.
Tip 2: Ask questions about the company's culture and what it will add to your career.
Tip 3: Ask about anything fun that the company does, this will help you understand aspects of the company outside of work
