Hi Yuvraj, hope your doing well!
I would suggest you go for Edureka's Selenium Certification. 
Do check it out  https://www.edureka.co/selenium-certification-training
I took it up too to start my career in automation testing.  This covers Selenium WebDriver, Selenium Grid, Selenium IDE, handling IFrames, Alerts, and Modal Dialog box.  In this, I also learned to use Selenium supported plugins such as TestNG Framework, Robot Class, Cucumber, and Gherkin to control your automation environment. 
It helped in getting a hands-on experience on frameworks such as Data-Driven Framework, Keyword-Driven Framework, Hybrid Framework, and Behaviour Driven Development (BDD) Framework.
Hope this helps!
