There are two interviews: the first is a technical interview about distributed computing and cloud computing, like Hadoop, Spark, and Elasticsearch. The second is an informal interview with the team.
3 rounds of interview.
Firstly an algorithm test at Codesignal. There were 3 questions.
- 2 algorithm question 1 sql. first one was easy. but second one seemed quite hard
- time 5 hours for code signal
Interview questions [3]
Question 1
As someone already shared in Glassdoor:
You are standing on a unique diamond-shaped platform composed of 5 tiles. These tiles are positioned at coordinates: (-1,0), (0,-1), (0,0), (0,1), and (1,0). From a starting position (xs,ys), you make random moves in one of four directions: left (decrease x by 1), right (increase x by 1), up (increase y by 1), or down (decrease y by 1). Each direction has the same probability and the direction of each move is entirely independent of previous moves. Determine the probability that you can reach a given destination (xe,ye) without stepping off the diamond platform.
You are given a starting number of 1. Your task is to reach a target number, t, using two available operations:
operator 1: operator_add: Adds a fixed number, x, to the current number.
operator 2: operator_multiply: Multiplies the current number by a fixed number, y. The objective is to reach the target number, t, by using these operations sequentially. Among all possible ways to reach t, pick the sequence that Maximizes the number of times operator 2 is applied Minimizes the number of times operator 1 is applied among all sequences that maximize usage of operator 2
I applied online. The process took 2 weeks. I interviewed at Agoda
Interview
3 interviews and a language test that is done online. HR was very helpful throughout the process and replied in a timely manner. The interview with the hiring manager however was last minute, long and some questions were invasive and irrelevant. The process took 2 weeks and after the final interview I received a rejection with no feedback. I emailed and asked for feedback since I did not expect to be rejected (I passed 2 language tests and the 2 other interviewers gave me positive feedback so I was curious to know where I went wrong). But I did not hear back from them. It was frankly a waste of time.
