BASICS which Tech Recruiters Should Know…


a) Product Based Company: These companies develop the own IT products based on the market needs and sells to the other company / release the product directly into the market. Ex: IBM / ORACLE / MICROSOFT

b) Service Based Company: These companies developing the IT products based on their client requirements. Ex: TCS / CTS / WIPRO..


a)FRONT – END: It will interface between the User and Backend… Front-End is responsible for collecting the inputs in various forms from the user.

b) BACK-END: It’s a Database which can be used by the End-User in-directly through external application. Use to store the database. Eg: SQL, Oracle, PSQL, Sybase, DB2 DB

3) SDLC: (Software Development Life Cycle) : It’s a structured Process which uses to develop the Software Products.

Testing Methods:

Whitebox Testing : Transparent box testing and structural testing) / Use to test the internal structures (Data Flow Testing / Branch testing / Path testing / Statement Coverage / Decision coverage)

Black-Box Testing : To test the functionality of the application without testing the internal structure (Unit Testing / System Testing / Integration testing / Decision Table Testing / Error Guessing)

Gray Box Testing : It’s a combination of White-box testing and black-box testing

 Testing Types:

Manual Testing : Manually testing the software defects (Role : end-User) which used to reduce the cost of the actual Testing. Unit Testing / Integration Testing / SW Testing (functional / non-functional) / System Testing / User Acceptance Testing / Release or Deployment Testing

Automation Testing : Using special software tool to control the execution of Test & Compare the Actual output with Predicted Output. (Functional Testing – QTP / Performance Testing – Loadrunner / Performance Centre / Software Quality Assurance – QC)
