MSG91 Implementation Consultant Interview: Rounds, Questions and Preparation

What the job involves

Implementation Consultants at Indian SaaS and B2B product companies help new customers set up and adopt the product, often working with APIs, dashboards, and integrations. They act as the bridge between sales, product, and the customer, ensuring smooth onboarding and resolving technical issues during the trial and post-sale period. Day to day involves customer calls, configuration, troubleshooting, and documenting best practices.

Role and Technical Knowledge

1. 1

   What is the difference between an API key and an OAuth token, and why would a SaaS product use one over the other?

   Explain that API keys are simple but less secure for user-level access, while OAuth tokens provide scoped, revocable access. Mention that for customer-facing integrations, OAuth is preferred for security and granular permissions.

2. 2

   How would you explain the concept of a webhook to a non-technical customer who wants real-time delivery updates?

   Use an analogy like a doorbell that rings when someone arrives, rather than you checking the door repeatedly. Emphasize that webhooks push data automatically, saving time and enabling instant actions.

3. 3

   What are the common reasons an SMS might fail to deliver, and how would you investigate?

   Cover DND, invalid numbers, operator issues, low balance, and template mismatch. Suggest checking delivery reports, logs, and account settings, then coordinating with support if needed.

4. 4

   Write a basic SQL query to find all customers who signed up in the last 7 days and have not completed onboarding.

   Show a SELECT with a WHERE clause on signup_date and a condition like onboarding_completed = false. Mention using date functions like NOW() - INTERVAL '7 days'.

Practical Scenarios

1. 5

   A customer's integration is failing because their server is not responding to our webhook. How do you troubleshoot and what do you tell them?

   Walk through checking webhook logs, testing the endpoint with a tool like Postman, and suggesting retry mechanisms. Advise clear communication: explain the issue, provide logs, and offer a temporary workaround like polling.

2. 6

   You have three customers waiting for onboarding help and limited time. How do you prioritize?

   Prioritize based on urgency, contract value, and impact. Mention using a simple matrix and communicating timelines to all customers to manage expectations.

3. 7

   A customer insists on a feature that your product does not support. How do you handle this?

   Acknowledge the request, explain current limitations, and offer alternatives or a workaround. Log the feature request and follow up with the product team, keeping the customer informed.

4. 8

   During a training session, the customer's team seems confused about using the dashboard. What do you do?

   Pause and ask specific questions to gauge understanding, then simplify your explanation with a live demo. Offer a follow-up session and share a recorded walkthrough or documentation.

Behavioural and HR

1. 9

   Tell me about a time you had to explain something complex to someone who was not technical.

   Use the STAR method. Focus on how you simplified the concept, checked for understanding, and achieved a positive outcome. Highlight patience and clarity.

2. 10

   Why do you want to work in implementation consulting, especially in a SaaS company?

   Show enthusiasm for solving customer problems and working with technology. Mention enjoying variety, learning new products, and helping businesses succeed.

3. 11

   How do you handle a situation where a customer is angry about a delay in resolution?

   Emphasize staying calm, listening actively, apologizing sincerely, and providing a clear action plan with timelines. Follow up to ensure satisfaction.

4. 12

   Where do you see yourself in two years in this role?

   Express a desire to deepen product and technical expertise, take on larger accounts, and contribute to process improvements. Show commitment to growing with the company.

Company and Sector Awareness

1. 13

   What do you understand about the Indian SaaS ecosystem and how implementation consultants add value?

   Mention the growth of Indian SaaS globally, the need for fast onboarding, and how consultants reduce churn by ensuring product adoption. Reference examples like CRM, communication, or analytics tools.

2. 14

   If you were onboarding a new customer for a communication API platform, what are the first three things you would do?

   Suggest understanding their use case, setting up sandbox credentials, and scheduling a kickoff call. Mention documenting requirements and sharing a timeline.

3. 15

   How would you keep up with product updates and industry changes in a fast-growing SaaS company?

   Talk about reading release notes, attending internal training, following industry blogs, and experimenting with new features in a sandbox. Show proactive learning.

4. 16

   Why do you think customer success and implementation are important for a B2B product's revenue?

   Explain that happy customers renew and expand, reducing acquisition costs. Implementation ensures value realization, which drives retention and referrals.
