I applied through an employee referral. I interviewed at DigiCert (Bengaluru) in Sept 2025
Interview
Applied through referral, Got shortlisted for an interview.
Received an e-mail from DigiCert asking for interview availability.
Round 1 was Scheduled
Round 1:- DSA Round
Usually in this round 2 questions are asked but I solved both with dry run and code in less than 20 minutes so was asked 3rd 😅, so I was pretty confident that I would clear this round 😬
In 2 days, i received an e-mail from DigiCert asking for round 2 availability.
Round 2 was Scheduled.
Round 2:- DSA + Design round
The same day, HR calls at night to schedule HM round, was to schedule the next day that was Thursday but I had another 2 other interviews that day, so she asked for Friday but my luck I had committed 1 more interview that day, I asked for Monday but she told other candidates were in pipeline, so I asked to schedule my interview in evening on Friday.
Round 3:- HM round, I was pretty sure I would clear this round, but that wasn't my day to say the least.
Started off by asking intro, followed by standard questions why you want to switch, why digicert etc followed by project discussion and then same Merge Sort (which I implemented) without extra space complexity which I am still searching for if anyone finds it please do send me 😅 and finally a puzzle was asked which I solved.
I had 50:50 feeling for this and that was friday night, trust me those 2 days till Monday when I can call the HR was one of the hardest times for me to spend ever (which by the way no one responded).

Q2:- Tower of hanoi, this question I solved way back in college days, I totally forgot it since in the real world these questions are not asked, so I tried to implement the solution then and there only and with some hints I logically solved it but due to time constraints couldn't code it.
Q3:- The main part, Design a courier tracking system like FedEx.
I applied online. I interviewed at DigiCert in May 2025
Interview
Round 1 - Mailed the HR for what the interview will be about but i didn't get the response as to what i was supposed to prepare for, so i skipped studying Dynamic programming and DBMS and put my time into LLD and to my luck both of the concepts got asked

I applied through a recruiter. The process took 4 days. I interviewed at DigiCert (Bengaluru) in Dec 2024
Interview
The entire process was communicative and transparent. Technical questions were scoped according to company role. Recruiter Suravi Shetty was proactive and helpful, which really helped during the entire interview process.
I was interviewing for frontend role, so my questions were mostly based on expertise in javascript with simple DSA questions. UI designing was also part of the interview.
