I applied online. The process took 4 weeks. I interviewed at Bloomberg (New York, NY) in June 2009
Interview
I initially applied online, and was contact by HR to do an online skills assessment test. The test was easy--it was multiple choice, and consisted of basic math problems, logic problems, and attention to detail. Each question was timed.
I completed this successfully, and was scheduled a phone interview. The interviewer asked about some projects that I had done, and after I mentioned a few, he made up many questions on the spot that related to my projects; why would such and such cause a problem, what if I had tried this instead, why wouldn't doing something a certain way make sense, etc. There was barely any feedback in either the positive or negative direction; the interviewer would often ask if I was sure about the answer I had given.
Following the phone interview, I was contacted for a timed technical test on a programming language of my choice. Difficulty of questions on this test varied very widely, though many were very high-level and heavy on nitpicky details. I assume this test was used mostly to gauge my level of knowledge of the language.
After completion of the test, I was contacted for an in-house interview.
Interview questions [1]
Question 1
(Programming Language Test) When casting an object of a polymorphic class from a base class, which kind of cast executes only if it's is valid?
I applied online. The process took 1 week. I interviewed at Bloomberg in Mar 2014
Interview
Applied in mid February. After a few weeks, received an email asking to set up a phone interview. I was re-scheduled for interview a week later. Then got a call from one of the software developers. Interviewer was very nice, kind and understanding. Asked questions about my prior software developing experience, basic C++ questions, etc.

Question 1
Average interview. Interviewer asked when do we use BST and hash table? What is the complexity of search or insertion for BST?

Interview
Applied online, got a phone interview. They had a lot of applicants; I believe the job is currently filled (2014).
Phone interview had only tech questions. Interviewee picked at my resume and posed in depth questions about SQL that I used for a project. I was stumped on some questions that I thought were unfair. (e.g. I was asked how I would implement a Foreign key constraint if I were designing that algorithm)
I was then asked for a sorting algorithm and Big O. Then how I would sort the array if I knew the range of integers.
Didn't know data structures/algorithms for interview and it hurt my interview...didn't receive an offer and I wasn't surprised.

Question 1
How would you implement a Foreign key constraint if you were to design it?
I applied online. I interviewed at Bloomberg (New York, NY) in Jan 2014
Interview
For the phone interview, I was asked for basic concepts about vector, array, linked list and their difference. Another question is given you a book, there is a function that you can get a word every time, how to find out the five words appear most frequent ?
Got the invitation for onsite interview the second day. There were four rounds, the first two were technical interview, the third round I saw HR, the last round was a manager.
1. There are consecutive numbers from 0 to 100, one is missing, find out which one? And improve the algorithm. How about using math method?
2. Search and sort question and improve accuracy.
3. Given you lots of left and right bracelets, how to test if the bracelets make pairs.
4. Delete a node in linked list.
