I applied through a recruiter. The process took 1 day. I interviewed at Dell Technologies (Bengaluru) in Nov 2018
Interview
Not sure about how many rounds. I was rejected in first round itself. Interviewer was not professional. Interview was not like a discussion, it was more like a question and answer session.
Below are the questions asked
1. How to avoid duplicate in Arraylist
2. What is the principal of micro services?
3. How do you move application to cloud?
4. When do we override equals and hashcode?
5. Difference between hashmap and hashtable?
6. What is the error when we add duplicate key to map?
7. Java8 features
8. How to use streams with list
9. How to implement pagination without Page object?
10. How to get an object from Arraylist if we have 1lakh objects?
11. How to avoid duplicate objects without overriding equals and hashcode?

13. Which DB suited for transactional data i.e continuously addition

15. new String ("a"), new String ("a") how many objects?

Interview questions [1]
Question 1
How to get an object from an Arraylist if we have 1 lakh objects?
Good and interactive. 3 rounds . Last one is techno manager round. But response from HR is less. Need to improve on that. Tight schedules. Coding and technical discussions especially on the projects.
Interview rounds were quick and medium-hard level, 2 Technical Rounds, 1 Mangerial Round.
Have to attend face to face interviews and not virtual.
DSA, LLD, HLD and behavorial aspects, all are evaluated thoroughly.

Question 1
System Design Question and explanation of current project in depth
A entrevista foi feita em três etapas.
A primeira foi a etapa da triagem inicial, uma conversa com o RH. Depois foi necessário gravar um vídeo de no máximo dois minutos me apresentando e esse vídeo seria enviado para a equipe nos Estados Unidos e na Índia da Dell, pois o projeto que eu iria trabalhar era na Índia e nos Estados Unidos.
depois teve um processo de validação técnica.
, na minha opinião, o processo para o procedimento para gravar o vídeo em ingles foi relativamente desafiador.
No final eu tive a resposta positiva. A parte de entrevista para minha apresentação com a equipe técnica foi feita de forma assíncrona, enviando um vídeo.
