Sprinklr India Software Engineer Interview: Rounds, Questions and Preparation

What the job involves

As a Software Engineer at an Indian SaaS or B2B product company, you will build and maintain scalable web applications, APIs, and microservices that power multi-tenant platforms used by enterprise clients. Day to day, you will write clean code, debug production issues, collaborate with product and QA teams, and optimise features for performance and reliability. You will also participate in code reviews, sprint planning, and on-call rotations to ensure high availability of the product.

Role and Technical Knowledge

1. 1

   What are the key differences between a monolithic and a microservices architecture, and when would you choose one over the other for a B2B SaaS product?

   Explain trade-offs: monoliths are simpler to start, microservices offer independent scaling and deployment but add complexity. Relate to multi-tenant SaaS needs like isolation and scalability.

2. 2

   How would you design a multi-tenant database schema for a SaaS application to ensure data isolation and performance?

   Discuss approaches like shared schema with tenant ID, separate schemas, or separate databases. Cover indexing, partitioning, and security considerations.

3. 3

   Explain how RESTful APIs work and what makes an API idempotent. Give an example relevant to a B2B platform.

   Define REST principles, HTTP methods, and idempotency (e.g., PUT vs POST). Use an example like updating a customer record or processing a payment.

4. 4

   What are the common causes of performance bottlenecks in a web application, and how would you debug and resolve them?

   Mention database queries, N+1 problems, caching, network latency, and profiling tools. Describe a systematic approach: monitoring, logging, and load testing.

Practical Scenarios

1. 5

   You are tasked with adding a new feature to an existing SaaS product that must not disrupt current users. How would you approach it?

   Talk about feature flags, backward compatibility, gradual rollout, testing, and communication with stakeholders.

2. 6

   A production bug is causing intermittent failures for a few enterprise clients. How do you troubleshoot and fix it?

   Describe steps: reproduce, check logs and metrics, isolate the issue, apply a hotfix, and conduct a post-mortem. Emphasise communication with affected clients.

3. 7

   You need to integrate a third-party API into your product. What factors do you consider before implementation?

   Consider rate limits, authentication, error handling, data privacy, SLA, and fallback mechanisms. Mention testing with mock servers.

4. 8

   How would you optimise a slow SQL query that is affecting the dashboard loading time for a client?

   Discuss analysing query plan, adding indexes, avoiding SELECT *, denormalisation, caching, and pagination.

   Give an example of a time you received constructive criticism. How did you respond?

   Demonstrate openness to feedback, action taken to improve, and positive result. Avoid being defensive.
