		Knowledge-based questions - picked 2 out of  6 categoires. 3 question per category.
				1. 		Production issues and scaling:
							* Given a graph of stats, CPU and memory usage. Figure out the issue.
							* Given the number of threads have become a bottleneck. why this is happening and a possible solution.
							* Given a service is currently handling 1 request/sec. What are the steps to handle 1000 req/sec.		
				2.     OOD:
							* Inheritance vs Composition.
							* Dependency injection.
							* Spring related question.										
		Coding:
				1.      Given a List strings, each string int the format <User_id,resource_id,ts>
						 Find each user’s start and end ts for accessing any resource. Solved in n^2 * logn
					
				2.      Follow-up. find which resource was accessed the maximum number of times in a 5 minute window. Return the count and the times at which it was accessed.(list of ts in that window).

		Knowledge-based questions I've answered clearly and took a little more time . (15mins. was supposed to finish in 10mins).
		Coding was able to finish 1st one. For follow-up, I've finsihed it but time ran out. Had I saved the previous 5 mins in the tech quesions would've solved it. :(
		
		I did not want to take a chance, so scheduled another attempt.

	Knowledge based questions - 6 (wrapped them in 10 mins).
	
	Coding:
				1. Given a count-to-domain map, return the aggregate count along with sub-domain
					Ex: Input : google.com -> 900, a.b.c.com -> 20 , b.c.com -> 30, c.com -> 10
						Output:  google.com-> 900, a.b.c.com->20,b.c.com->30,c.com->10,com->960
						  
				2. https://leetcode.com/discuss/interview-experience/1713353/karat-interview-experience-indeed
				
				1st question I had trouble in forming sub-domains, one key thing is java string.split() takes regex, I was seperating by "." but the regex should be "\\." (interviewer helped with this.) Took 33 mins to solve this. :( 
				
				2nd question. Wrote the code(I've already did it before). But no time to test.
				
	Note: Indeed's karat interview is really good and easily crackable. They just need the right answer(need not be optimal).
			   Interviewers are really friendly and are completely involved.

	Will I be considered for on-sites?
