If you flip 400 coins, what's the probability of getting more than 220 heads
The interviewer didn't know anything and asked me to sort a general array in O(N). He even didn't know about the top-down approach and bottom-up approach in dynamic programming.
Suppose you have three call options on the market, with strikes 10, 20, and 30. Suppose the call option with strike 10 costs $12, the call option with strike 20 costs $7, and the call option with strike 30 costs $1. Does there exist an arbitrage opportunity?
flip a fair coin, what is the expected number of times one need to flip to get two consecutive head.
What are your salary expectations
Explain the scenario where you helped a colleague at work
The interviewer started with some small talk. Talked a little bit about my research work. Then went on with technical questions. Openned terminal on his computer. First he asked about if I know anything about zombie process. Then he asked about ‘malloc’. Then he told me, how would I implement a malloc like function in a separate memory space like some PCI connected to the main memory. The question was not very clear to me. I tried to explain how I could implement that memory over the extra connected memory. I am not sure if he was very happy about it. Then he went onto his terminal. A C program was there. Just two lines char* str1 = “string1”; char str2[] = “string2”; He told me to print the two strings. I did and then he told me to change the ‘t’ in both of the string to ‘T’. I told him that we cannot change the first string. He asked me why? I could not tell it clearly. I just showed him that, it generates a segmentation fault. I told it might be in some place in the memory which we cannot edit. He kept asking the question to prove my point. Then gave me hint and let me print the addresses of main, some variables which have higher value sounded like they are in the stack part. Printing the values of main showed very low address which shows that, it’s in the code segment. The char* variable was in a little more higher address which clearly shows that, it is in the data segment, which suggests that we can not edit anything on the data segment. So need to know what’s more there in the data segment? Then he showed some networking terms ip ipconfig ping some more (around 6-7) which I forgot. He told me to explain in short what these functions do. Then he asked me to write a script on python, which will read a file and add all the numbers on the third column. He showed me the file with cat command. It as a space separated text like 1 7 8 9 6 5 5 0 8 8 4 5 7 2 4 6 8 9 0 7 4 5 1 7 9 6 0 3 8 0 1 7 8 9 4 6 8 0 8 6 9 8 6 9 7 0 7 6 4 0 1 2 3 4 5 6 7 8 4 5 6 7 8 9 1 0 1 3 4 8 3 5 1 7 8 9 4 6 8 0 8 6 9 8 6 9 Then he gave me a problem on linked list. The problem was to delete all the nodes with a particular number on it. I just needed to write the main function and call that from the main file. The structure and main file was already written. I just needed to add the function prototype to the *.h file.
Why Allianz? Why this specific position? Situation when you had to deal with a problematic client? What role do you take in a group? How do you see the future of the asset management industry? And some other questions related to interaction of asset management, insurance companies and current market situation?
