Tell me a technical challenge you have faced during your work and how you tackled it.

Example 1:

 In My previous organization we had to Migrate our database from MySQL to Postgres in a very short time which would impact the data of existing customers. It was my first time doing Migration testing and it was challenging as any mistake in testing would break the build on prod environment. Since, I was the most experienced on the product and was also an Individual contributor, I had to come up with strategies and analyze the impactual areas, create dummy data and perform migration testing on this dummy data dump. I had to consider many factors like the impact on UI after migration, Data loss, and analyze how the data was stored in the new database, like is data stored in proper format, does decimal fields have same precision as in the old DB, the performance of the application after migration etc.


Example 2:

As we know in agile the focus is deliver the functionality as soon as possible. So there was very less time spent on UI/UX and people were very focused on delivering functionality. This was a challenge because there was a lot of re-work involved since every time the user would find some UX issue and then we had to re-work on it.

   Jenkins Architecture: Jenkins follows a Master/Slave architecture where master and slave communicate over TCP/IP protocol Jenkins Architecture has 2 main components: 1. Jenkins Master/Server          2. Jenkins Slave/Node/Build Server 1. Jenkins Master: The Main Server of Jenkins i.e. the brains is the Jenkins Master It is a dashboard which is powered from a war file Runs on port 8080 by default With the help of the dashboard we can configure the jobs/projects but the build takes places in the Node/Slave server By default one node is configured and running in Jenkins Server We can add more nodes using IP addresses, username, passwords using jnlp, ssh or webstart methods The main job of server is: Scheduling build jobs Dispatching builds to the nodes/slaves for actual execution Monitoring the nodes/slaves Recording and Presenting the build results A Master/Server instance of Jenkins can execute build jobs as well i.e. it can also act as a node itself 2. Jenkins Slave: The Jenkins sla

Why do we need a build tool?

Why we need build tool? Consider this scenario where you want to run a java application   You can use java compiler (javac) provided by JDK to compile java code into Byte Code which can then run on any Machine To compile Java Programs using javac you will have to list all java source files to run the entire application Ex., "javac Program1.java Program2.java Program3.java Program4.java" This is a very tedious job. Doing this manually is a pain since there are hundreds of libraries used even in the simplest of Java Application Also one has to add Compilation classpath to make the code work. For example if the code uses libraries like testNG, Selenium etc. You need to add it to Compilation Classpath using following code: "javac -cp testNG.jar; webdriver.jar; lib3.jar" MyProgram.java In conclusion, Compiling java code manually becomes very tedious and complex task Enter Third party build tools like Spring boot, apache-comm
