No coding questions are shared, only interview structure and personal suggestions.
First, go to the Mountblue website and read everything about hiring also the FAQ and join the discord channel with the link provided there and read channel instructions which cover almost everything.
I’ll divide the total hiring process into 3 steps, as hiring takes between 2 to 5 months(or more).
STEP 0:
I went to the Mountblue company website and applied using the email that’s it they don’t even ask for a resume as they are only interested in your problem-solving and coding skills. Immediately I received an automated mail from Mountblue which contained a link that directed me to the Hackerrank coding challenge. I created a Hackerrank account and started solving 122 challenge problems and completed them by Dec 19th, 2023. After completing 122 problems with all test cases my challenge rank became 1 just like 100s of other students now I am qualified to apply for the next round. Then I went to my hackerrank profile page on my laptop took my profile screenshot and applied for the next round with a link you can find in the discord channel instructions. After 20 days I received an email that said something like “As there are many students who submitted challenge we’ll arrange an interview soon “. This is where actual hiring starts because now they’ve considered your profile as they’ve verified your Hackerrank challenge.
- you can take a minimum of 15 days to complete all 122 problems and a maximum of 100 years
- I suggest learning how to solve patterns first. You can search for “striver solve any pattern” and “kunal kushwaha solve any pattern” on YouTube for help
- All test cases must be passed. If some test cases are timing out, that means you need to come up with an optimal solution. Try using inbuilt functions. If you’re stuck, try using YouTube or the discussions page. Focus on a learning approach rather than just solving for the sake of finishing the challenge.
- Make sure to provide your hackerrank profile URL while submitting not just the profile name. Copy the profile URL and paste it incognito to check if your profile is showing or not if not then solve two dummy problems in hackerrank other than the challenge now again check if the profile URL is working in incognito. If it works then only your submission will be successful
- After submitting you need to wait a minimum of 20 days (up to 50 days)to receive mail.
STEP 1:
On Jan 13th I received an email that asked me to select an offline interview location either Bengaluru or Delhi NCR. On Jan 15th I received an email confirming the interview location and time with a Google calendar invite which is Feb 3rd at 11.30 AM Bengaluru.
- Only offline interviews, online interviews are ended no use try mailing them
- If you want to reschedule your offline interview because of any reasons like exams or GATE, you can mail them but there is no guarantee
- You need to wait a minimum of 15 days (up to 60 days) for an interview date.
- Syllabus for TR interview: patterns, arrays(build functions), 2D arrays(matrix), strings(inbuilt functions), hash-maps(dictionaries or whatever they are called in other languages) and solve as many models as you can in Leetcode and other platforms like hacker rank, CodeChef mostly easy problems, once you’re comfortable, go to medium problems. As it is an entry-level job they only have easy and medium problems. If you have time also learn the pointer technique(very important in general), the sliding window technique, greedy algorithm approach(easy problems) and then you can crack. Don’t forget to revise.
STEP 2:
On Feb 3rd morning I arrived at the Mountblue office which is not difficult to find with Google Maps as the location is a well-known area. Try to come to the location at least 1 hour before. I arrived at the location by 10 AM, there was enough space in the office to sit and relax and complete the final revision. The interview process started they gave us 1 pattern problem on paper and asked us to write pseudocode along with the name and time we started solving a problem they’ll consider the time taken to solve the problem, and after completing that you need to show it to sir after verifying sir asks you to execute it I used local IDE you can use VS-code or local IDE or any online IDE no problem. After sir verifying your output they give you another problem on paper you’ve to write pseudocode and the time you start and the process continues after completing some 5 or 6 problems they’ll tell you you’re selected for the final round and wait fa or non-technical assessment mail, i received the mail by evening same day. Some students who were informed that they’ve been selected haven’t received non-tech assessment mail yet which means their applications are on hold.
- If they didn’t tell you that you were selected and wait for further mail, that means you are rejected they don’t send rejection mail
- The interview process is flexible they’ll modify it according to their convenience.
- There is no exact time limit to solve the problem but if you take so much time they may put your application on hold or even reject it. Try solving under 40 minutes, 1 or 2 problems can be solved under 15 minutes if you’re very comfortable with basics and inbuilt functions.
STEP 3:
After reaching home I completed a non-tech assessment which took around 15 minutes and contained a few questions like what programming languages you are comfortable with and a few questions you need to give video responses like what you know about Mountblue, and what technologies have you learned apart from the college curriculum. Make sure the audio is clear and the internet is good you can give a video response again if there is any problem there are two options submit or retake. After 2 days I received an email saying your non-tech assessment was completed successfully and to give us 7 to 10 days to share the result.
Now I am currently waiting for the selection mail.
