This guide breaks down the role in simple terms — who it’s meant for, what skills actually matter, where candidates usually go wrong, and how B.Tech students can realistically prepare to get shortlisted.
Job Overview
Role: Software Development Engineer in Test (SDET)
Department: Information Technology
Category: Technology, Analytics & Digital Banking
Location: Chennai, Tamil Nadu
Req ID: P-179163
Company: IDFC FIRST Bank
This is a hands-on engineering role, not a support or documentation-heavy QA position. SDETs here work closely with developers, product managers, and platform teams to ensure quality across production-grade systems.
Who Should Apply?
Primary Fit: B.Tech Students & Freshers (0–2 Years)
This role is best suited for:
B.Tech students or graduates from CSE, IT, or allied branches
Final-year students with testing, automation, or backend-heavy projects
Freshers who have practiced manual + automation testing, even through self-learning
This is not meant for absolute beginners. While industry experience isn’t mandatory, the bank expects some real hands-on exposure — college projects, internships, or serious personal projects are enough.
Secondary Fit: Early-Career QA Professionals
Also relevant for:
Manual testers looking to move into automation
Junior automation engineers wanting exposure to large-scale, regulated systems
| Target Profile | Exposure Expected |
|---|---|
| Junior Automation Testers | Banking or fintech systems |
| Junior Automation Testers | CI/CD-driven testing |
| Junior Automation Testers | Large-scale applications |
For many candidates, this role can act as a launchpad toward Senior SDET positions, which IDFC FIRST Bank actively hires for.
What Does an SDET at IDFC FIRST Bank Actually Do?
Test Planning & Design
Convert requirements into structured test plans
Design test cases for web, mobile, APIs, and databases
Work with developers to understand edge cases and system flows
Automation Testing
Develop and maintain automated test scripts (Selenium, Appium)
Execute automated regression and sanity suites
Decide what should and shouldn’t be automated
For freshers, hands-on practice matters more than knowing every framework.
Manual Testing
Perform functional, regression, and exploratory testing
Log defects with clarity and reproducible steps
Validate fixes during sprint cycles
Even in SDET roles, manual testing remains critical.
Web, Mobile & API Testing
End-to-end validation of web applications
Mobile compatibility and behavioral testing
API testing and integration validation
Basic API testing using tools like Postman is a strong advantage.
CI/CD Awareness
Run automated tests as part of CI pipelines
Enable early defect detection
Improve overall release confidence
Freshers are expected to understand CI/CD concepts, not architect pipelines.
Database & SQL Validation
Run SQL queries to verify backend data
Validate data integrity and transformations
Identify data-related defects
Basic to intermediate SQL is more than enough.
Skills That Matter for This SDET Role
Must-Have Skills
Manual and automation testing fundamentals
Selenium or Appium
API testing basics
SQL fundamentals
Agile / sprint-based workflow understanding
Clear communication and documentation
Good-to-Have Skills
| Skill | Why It Helps |
|---|---|
| CI/CD basics | Signals production readiness |
| Banking / fintech awareness | Strong domain advantage |
| Real testing projects | Proof of execution, not theory |
Resume Tips for B.Tech Candidates
Recruiters focus on what you’ve actually built or tested, not certificates.
What Works Well
Tools you’ve genuinely used
Automation or testing-heavy projects
Collaboration with developers (even in college projects)
Sample Resume Bullet Points
Automated regression test cases using Selenium for a web application
Tested REST APIs using Postman and validated responses with SQL queries
Worked with developers during sprint cycles to improve test coverage
Common Reasons Candidates Get Rejected
| Reason | Why It Hurts |
|---|---|
| No automation proof | SDET roles demand execution |
| Weak SQL knowledge | Banking systems are data-heavy |
| No real projects | Certificates don’t replace practice |
| Poor bug documentation | QA clarity is non-negotiable |
Accepted Educational Qualifications
B.Tech
BCA / MCA
B.Sc / M.Sc
M.Tech
Among these, B.Tech candidates align most naturally due to engineering depth and system-level exposure.
