Round 2(Technical Interview 1 – 60 min):
- Introduce yourself.
- Given an unsorted array with duplicate elements. You have to remove the duplicate elements without using a built-in data structure(Java Collection Framework or C++ STL Library). The interviewer mentioned that you can use the data structure that you can build on your own like Array, LinkedList, etc. Only the approach was asked not code. https://afteracademy.com/blog/remove-duplicates-from-an-unsorted-array
- Write an SQL query that prints city names along with the number of citizens in it. The scenario was something like that two tables are given, the city names were in one table and no of citizens were in another table and there is a common attribute in both the tables(foreign key concept).
- What are Convex and Concave Polygon?https://www.geeksforgeeks.org/types-of-polygons/

Rich UI: It consists of unique images and videos for all similar types of products. AddOns are automatically suggested in this UI and based on that you add up things in your order like ketchup, sausages, etc.
Minimal UI: It consists of similar images and videos for all similar types of products.

- Which UI will be better for your App even though it is mentioned that development time and App loading time and cost measures will be high for Rich UI?
The first round of interview was over with this. He asked if I had any further questions.
Suggestion: The interviewer suggested that whenever you mention a publication in your resume, you should include the link as well.
Tips: While introducing yourself use sir/ma’am in some of the sentences so that they respond. The benefit from this will be it will look like a conversation instead of a paragraph.

(He mentioned that Brute Force Approach is also allowed).https://www.geeksforgeeks.org/check-whether-two-strings-are-anagram-of-each-other/
