Interview Preparation Tips

Interview preparation tips for other job seekers - I have appeared on Techgig challenge and get a call from HR regarding Software development Java position.
First round is scheduled on Barraiser and is taken by Third party person. In these round, first interview give me a question to print anagrams from list of strings and to be printed of same type in different line. I have started by discussing the approach and then after 20-30 mins, I was able to reach the optimal solution. Then he discussed me about my project that I am working in current company and tell me to draw the architecture diagram.
After 2 days, I got the call from the HR and selected for 2nd round technical interview with Technical lead.
First time, they have postponed the call which is scheduled on Google meet.
In second time, the interviewer joined and round started with introduction of both and the interview tell me about the company and how it is growing and all.
Then we move to technical discussion. First he asked me about what are features are added in Java 8, then one by one concepts of Java regarding threading, producer-consumer problem.
After OOPS concept discussion, he gave me two DSA problems to solve in optimal way. I am unable to do that since I have not gone through it.
In the interview, I am pretty sure that I am not selected for the next round as my DSA is weak.
And after interview, I have never received any call nor any mail regarding my rejection and feedback.
