I applied through a recruiter. The process took 1 day. I interviewed at Informatica (Bengaluru) in Apr 2016
Interview
The TA guy wanted me to attend the interview immediately and I quickly scheduled one and went there for one full day. And after that I never got a call back for about a week. And later when I called asking for feedback, he says the position for which I was interviewed is waiting for approvals and that he ll get back in a couple of days. Again no reply,later when I called again he said the approval doesn't seem to move fast and hence I can look outside for other opportunities. If they don't have any approval in hand, they shouldn't have wasted my time.
very disappointing. A very non responsive and irresponsible TA team and not the right way to treat a senior engineer.
I was asked to come to Bangalore office for a whole day 1-1 interview. Had about 4 tech rounds including the manager round. First round was on DS , second on Java , third on design
Interview questions [1]
Question 1
Round1 : DS
The interviewer was unprepared(usual thing) and opened Geeks4Geeks and asked these questions in random.
And even after I arrived at a solution, the interviewer was reading the material to understand the solution himself.PATHETIC!
1.Convert BT to BST
2.Check if a BT is a mirror tree
3.Check if a queue is a circular one.
4.Given a String and a pattern, find out the no of occurences of that pattern in the string.
5. Graph Adjacency matrix
Round2 : JAva. Was an interesting and the interviewer was pleasant.
1. Implement ReEntrant Lock in java
2. Equals and Hashcode importance in hashmap key.
3. Hibernate caching
4. PermGen and Heap and stack spaces - when where and how the memory is used.
Round 3: Design - The interviewer looked disinterested and asked for the sake of asking. Am sure the interviewer herself doesn't know anything about designing an application.
1.Explain REST Service.
2.REST vs SOAP
3.Out of memory and Memory Leak
4.Design a eclipse IDE (classes, entities, etc)
Round4 Manager -
When asked what tech was used in the project, he kept saying core java. I asked any frameworks, he said its plain java.Either he doesn't know what his team is doing or not interested to answer that question.Looked busy/pre occupied and was in a hurry to close the interview. No eye contact with the interviewer while i was trying to prpose a solution.
Behavioural questions mostly
And given a sequence of numbers, how many inorder traversal trees can be created w/o modifying the sequence order.
eg X Y Z
Find the no of tree structures that can be created from this sequence whose inorder traversal doesn't modify the order of the sequence given.
There are two rounds of technical interviews, one round of managerial interview and one round of HR interview. In first technical round it will be basic java questions, coding, unix and rdbms questions. Second technical round would be case study, real time scenarios and difficult coding questions.
I applied online. The process took 4 weeks. I interviewed at Informatica (Bengaluru) in Apr 2023
Interview
Quiet exhausting and not worth it. It was 8 rounds of interview. Where in 5 were technical. 1 techno managerial 1 with director and 1 with HR. No interview was started on time. There were so many last moment changes on timings. Most interview are stretched 30-30 min even more than the allocated hours.
The whole process took 1 month. After releasing the offer letter break up. They called after 2 days that the required is freeze.
Not recommended. It’s unreliable. Thank god I didn’t drop papers at my current organization after receiving offer letter.
