Technical Behavioral
I went through three interview rounds. I passed the first two rounds which seemed to align with the job description. The third round with the department head was where things got strange. They had different expectations and it felt like they wasted my time with multiple rounds. In the end, I was told my profile wasn't a match. I'm not sure what hiring process they follow, but it's definitely not one that screens candidates properly before multiple rounds. My suggestion to the department head is to not select candidates for any round if their profile doesn't match, to at least save the candidate's time. Big thanks to the HR team though, they kept me updated and gathered feedback after each round.

Behavioral Technical
First, there was a screening call with HR. They explained what the company does, and we talked about salary expectations. Then, a technical round focused on my resume, where I discussed a couple of projects with a team member. After that, there was a supposed CTO round, which was a brief 5-10 minute phone call. I felt like the CTO made a quick judgment. Then, I was ghosted by HR after trying to follow up, leaving me in limbo. Honestly, if you value yourself, just skip this company.

Behavioral Other
The interview process began well, with enjoyable conversations with both the recruiter and the hiring manager. However, the next step involved completing a substantial unpaid "case study" intended to demonstrate my skills. While I'm usually open to such assignments, this particular task was for a feature the company had recently launched. This raised concerns about potential work theft, and despite the possibility of harmless intentions, the situation felt uncomfortable. I communicated my concerns and reasoning in an email to withdraw my candidacy, after which I received no further communication.

Coding Technical Technical
The interview process included an initial coding test, followed by two rounds of in-depth technical interviews. The first technical round was conducted by a technical lead from the development team, and the second was with the Engineering Manager. Just so you know, the interview difficulty at Sirion for this role is quite high, so make sure you're well-prepared.
