I recently interviewed for an SDE II Backend Engineering role at Syfe, India.

📝 Application

I found about that role on LinkedIn and applied directly through a LinkedIn message to the recruiter.

After a week, I received a call to come to the office for face-to-face interview.

📞 Round 1 — Low Level Design

⏱️ Duration: 60 minutes

This was an elimination round. It was on LLD design. I was asked to design the LLD of:

• A stock brokerage system, with emphasis on allocation and de-allocation of stocks from client to system and system to stock exchange.
• I have to write the classes, show the relationship, write the DB schema, mention the Design Patterns and write 1 method() on the white-board.

✅ Result: Hire

After this round, I was moved to the 2nd stage round

💻 Round 2 — High Level Design

⏱️ Duration: 45 minutes

This was an elimination round. It was on HLD design. I was asked to design the HLD of:

• An app similar to ChatGPT with emphais on how token limit is reached by user, handling multiple user profiles and authentication flow.
• I explained everything and talked about caches, DBs, APIs, protocols. Basically I had to inform about every design decision. Eg; why WebSockets, why not SSE. Why SQL, why not NoSQL. Why a cache here and not there.

✅ Result: Hire

After this round, I was moved to the final interview round

💻 Round 3 — High Level Design

⏱️ Duration: 60 minutes

This was an elimination round and final round with the CTO. It was on HLD design. I was asked to design the HLD of:

• A flash sale for e-commerece. Eg; Flipkart Big Billion Day with special emphasis on handling and sending millions of notifications on that day.
• I explained my design but there were lot of questions on scaling, resilience and other non-functinal requirements, which I think I did not answer satisfactorily.

❌ Result: No Hire

📌 Final Outcome

❌ Rejected

I am currently also in interview loops with 2 other companies. I'll share the interview experiences for those companies as well once I have the final outcomes. 🚀
