Intercontinental Exchange Lead Developer interview questions

Interview process is tough and comprises of multiple rounds. Online written followed by multiple rounds of coding/ tech interview. And after you clear then behavioral round of interview and then you get offer. Still you can negotiate on salary but not a lot

I had read the bad reviews but had to experience myself to truly believe it. For the in-person java test, they asked question about inserting a node in a BST. Here is the problem, I provided a working iterative solution but the person knew only recursive and to my horror he said the only way it would work is through recursive. The irony is, I have been working with complex BST traversal at work recently so this question was luckily trivial but was dumb-founded to not even able to explain or demonstrate the solution. There were other questions and they were all standard ones but subjective.
