Tip 1 : If you are a newbie to programming, I will strongly recommend to practice LC/GFG/CodingNinjas Easy questions for clearing the basics. Once you gain confidence, you can move on to tackle medium and hard questions.
Tip 2 : Most companies require individuals to know System Design well. For somebody with 1-3 years of experience, database designing (identifying entities, their relationships and constraints), OOP concepts and API designing for Low Level Design is a must. I would recommend the "System Design Interview by Alex Xu" book for HLD preparation.
Tip 1 : Have an updated and properly formatted resume
Tip 2 : The resume tells your story so you ought to know and be able to explain whatever you've written.
Tip 3 : Do not include technologies/skills that you've not worked on at all. It can blow the interview if the interviewer questions you about it.
This was a technical round in the evening with a Software Engineer II which included a coding question along with a few questions on Core Java fundamentals.
I was given the option to either go for the coding round first or java theory. I realised that I might need more time for coding so I decided to opt for the coding round first, followed by the java related questions later.
The interviewer was extremely pleasant to speak with. He initially asked me to introduce myself and we spoke in depth about a project I worked on in my last organisation. The coding question was given on a google sheet but I was asked to code it on an online IDE without any special syntax correction features.
1. What is immutability?
2. Is try with multiple catch allowed? Explain.
3. What is garbage collection?
4. Tell me a little about HashMaps.
This round was in the evening with a Senior Software Engineer. He introduced himself and immediately presented the question on Google Doc.
I was asked to design a Food Delivery App (Swiggy). This round revolved around designing database schemas. I was given around 20 minutes to identify the various entities involved in the system, establish the relationships between these entities and also identify the primary key - foreign key constraints. After 20 minutes, we had a good discussion on my findings and corrections with respect to c...
This was a half an hour round with a Senior Manager.
