Got Rejected In an Interview, Just Because I Didn’t Answer a Personal Question
So, I got invited for this interview, and they told me to be there at 9 AM. Of course, I get there early, like 8:30, because I don't want to be late. But then I end up waiting for 1.5 hours. Seriously, they didn't even acknowledge me until 10. Then this HR lady calls me in, and she's totally unprofessional. She's like, on her phone, making personal calls while I'm sitting right there. And then she starts asking me these really weird questions, like what my nickname is, and what my dad does for a living. It got really uncomfortable when she started pressing for details about where my dad works. I mean, what does that have to do with anything? So I politely told her I didn't want to answer, and she actually said, "Then we can't continue this interview." I was honestly shocked. But instead of arguing, I just stood up and said, “Alright then.” And walked out. I left feeling pissed. Not only did they waste an hour of my time, but the HR rep was also rude and unprofessional..

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.

Interview Preparation Tips

Interview preparation tips for other job seekers - Round 1 - Technical: The first round involved solving one tree-based question and one array-based question. I was also asked about object-oriented programming concepts, Git commands, and SQL queries. In addition, I faced questions based on my resume projects, and I was asked to explain the difference between a primary key and a unique key.

Round 2 - Technical: The second round focused more on system design and APIs. I was asked to explain the difference between PUT and POST in REST APIs, design the database schema of one of my projects, and discuss inheritance and access modifiers (public, private, protected). Git commands were also covered. A scenario-based question was presented: "How would you send an email to a million users, ensuring that if an email fails, the system retries sending it three times? If the retries fail, the system should move on to the next email. Additionally, if the system crashes after sending 1000-2000 emails, how would you ensure that upon restart, it resumes from where it left off without resending emails?"

The HR was friendly, clearly explained the next steps, and provided constructive feedback. Overall, it was a positive interview experience.
