This is internship season back at KGP (Kharagpur). One of the companies to visit the campus was Bidgely, a startup by 2 IITians in Sunnyvale. I thought it might be a good idea to write down how it all went down.
The first round was a hackerrank test of 30 minutes, in 2 sections. Section 1 had 7 MCQs with marking scheme (+5, -2). Section 2 comprised of 2 coding questions, relatively easy to solve, but due to limited time, I don’t think anyone could’ve completed both.
Luckily I got shortlisted in the first round, along with 5 others. I had applied for Data Scientist profile. The other profile was Software, for which 3 people were shortlisted. The second interview was over Skype. The 2 other applicants had a video call with people from Bangalore. They were asked to explain the algorithm for a single question, and some puzzles.
I had an audio call with someone from Berkely, US. Due to connectivity issues, my interview which was supposed to go for an hour was winded up in 40 minutes. 2 questions were asked.
Given a number n, you need to print all permutations of numbers upto n. Say n = 3, you need to print [1,2,3], [2,3,1] and so on. I was asked to explain the pseudocode first on collabedit.com, and then write proper functioning code. I took time to write down the code, but since my interview was delayed, the interviewer asked me to complete the question after the interview and send it to him.
The second question was based on ML, of which I had not done much. Given the graph of a dataset looks like V, and the equations as: if (x > x0): y ~ a1x + b1 + noise1 else: y ~ a2x + b2 + noise2 How will you fit this model for these 5 parameters? I had no idea what the question meant, so he dumbed it down for me. I answered. He wasn’t satisfied. In this question, if the 2 lines were both positively sloped, how would you solve it? What would be the complexity of such a solver?
Overall, it went OK. A day later, the results came in. No one was shortlisted for Data, only one for Software :/
