Quantiphi Software Developer interview questions

First of all aptitude test was conducted after that workshop based on Firbase and Https then after a month they called for interview at their office. Whole process conducted by qdemy.

The Technical Interview started with questions about my resume. After that, the interviewer asked me about my intersts and future plans. We got started with the basics of Java and SQL. Towards the end, he asked me some puzzles which were nice ones. The HR Round included some technical questions about ML. Also, "Why Quantiphi?" was there because an HR interview is incomplete without that question I think. He also asked me how many Jockey underwears would be sold in a day in India, a guestimate. I approached the question starting with the population of India. I think I was not confident enough so I didn't make it through.
