Atlassian Interview Expertise for Summer season Internship (On-Campus)

Atlassian visited our faculty for hiring summer season interns. The eligible branches have been CSE, ECE & EE, and the C.G.P.A. needed to be larger than 7. The hiring course of consisted of three rounds – The coding Spherical, the DSA interview Spherical and the HR spherical. All of the rounds have been eliminatory.

ROUND 1: CODING ROUND
This was a written spherical carried out on the HackerRank platform. 3 questions had to be solved inside 90 minutes. The spherical was proctored, and the digital camera and microphone have been ON.

• The primary query was based mostly on Binary Search – https://www.geeksforgeeks.org/queries-counts-array-elements-values-given-rang/.
• The second query was a bit difficult and tough. It was like we’re given an array of named instructions which consists of the letters ‘L’ and ‘R’. Let its dimension be n. Then we calculate 2^n. After that, we take low as 1 and excessive as 2^n. After that, we run the loop n instances(suppose the loop variable to be I ), and every time we should take into account the mid of high and low, and relying on that worth we now have to insert I in our reply vector. After that relying on whether or not instructions[i] is ‘L’ or ‘R’ we now have to both take into account the left half, i.e., low -mid, or the suitable half, i.e., mid to excessive. I felt this query was probably the most difficult of all of the three however lastly I used to be ready to determine what wished.
• The third query was like we got an array of arrays of format : [ [ taskNo, ItemID, TimeLimit] ] and a variable known as ExpiryLimit. If the taskNo is 0 then we have to add the ItemID in our checklist with the Time restrict of its expiry as TimeLimit if taskNo is 1 and if ItemID is already current in our checklist, then we now have to test if the current time is inside TimeLimit of that merchandise if sure then we now have so as to add ExpiryLimit to its TimeLimit. Lastly, we needed to return the variety of Gadgets nonetheless unexpired after processing all of the duties.
