💰 Salary Range

As a market reference, Glassdoor currently reports CoinDCX Sr. SDET compensation averaging around ₹24.8 LPA, with a reported base range of approximately ₹23.8–₹25.9 LPA based on nine submitted salaries. The available data is marked low confidence, so it should not be considered an official offer range.

For this 3–7-year role, candidates could reasonably target approximately ₹18–28 LPA, depending on experience, automation depth, current CTC, mobile expertise and interview performance.

🎯 Preparation Tips

📱 1. Master Appium

Don’t prepare Appium only theoretically. Be ready to explain:

• Desired capabilities
• Android vs iOS automation
• Locators
• Hybrid applications
• Context switching
• Gestures
• App installation/reset
• ADB commands
• Handling flaky mobile tests

🔗 2. Practice API Automation

Prepare practical Rest Assured scenarios involving authentication, headers, request payloads, JSON validation, response codes, schema validation and API chaining.

☕ 3. Revise Java Coding

Expect questions around OOP, collections, strings, exceptions, interfaces, inheritance and basic coding problems.

🧪 4. Framework Architecture

Be prepared to draw your automation framework and explain how you handle Page Objects, test data, utilities, reporting, parallel execution and CI execution.

💰 5. Understand FinTech Testing

Learn concepts such as market orders, limit orders, deposits, withdrawals, wallet balances, transaction status, authentication and transaction failures. A previous CoinDCX Senior QA interview report specifically mentions questions around manual testing concepts, live automation coding and finance-product concepts such as market and limit orders.

Round 2: QA + automation technical interview
Round 3: Java/API/Appium practical or coding discussion
Round 4: Managerial/engineering discussion
Round 5: HR/final discussion

Add measurable achievements such as:

• Number of automated test cases
